Answer: Trigonal bipyramidal, ligands are at positions 1, 6, 2, 11, and The diagram shows the combination of s donor and p donor effects. What would you expect its magnetic moment to be? Would you expect it to be paramagnetic or diamagnetic? However, square planar is usually low spin and tetrahedral high spin.

Despite the LFSE results, I would expect tetrahedral, which is usually found for high oxidation state metal halides due to the size of I and its pi donor capability. For square planar, the same. Linkage isomerism --isomers in which the same ligand is attached by different donor atoms, e.

The ligands will be called by different names depending on how they are connected to the metal. Circular Dichroism —A form of electronic spectroscopy used on chiral compounds, which determines the specific rotation of circularly polarized light as a function of wavelength.

Pi back bonding —Donation of metal d orbital electrons to empty ligand orbitals that have a pi symmetry with respect to the bonding axes. A solution of this salt is also pink and rapidly gives 3 mol AgCl upon titration with silver nitrate solution.

The purple solid releases two of its chlorides rapidly; then, on dissolution and after titration with AgNO 3releases one of its chlorides slowly. Deduce the structures of the two octahedral complexes and draw and name them. Explain the color change. Answer: The pink solid ispentaamineaquacobalt III chloride. Chloride is a weaker field ligand than H 2 O, so the second complex is likely to have a smaller value of D O.

This means that it should absorb a lower energy color. According to the color wheel, the pink complex red should absorb green, and the purple violet complex should absorb yellow. Yellow is lower energy than green, as predicted. Answer: H 2 O has a medium ligand field strength, so its D O will be an intermediate energy. Label the 5 d orbitals and the energy ordering you would expect, and show or explain why.

The d z2 orbital extends toward the two ligands and will have the most overlap, leading to the orbital with the most antibonding character.

The d xz and d yz can overlap only in a pi fashion with the ligand orbitals, which tends to have less overlap, leading to again an antibonding character and rise in energybut less so. Finally, the d xy and d x2-y2 orbitals have only delta symmetry with respect to the ligands and will not be affected. The strongest interaction would be between the ligands and the d z2 orbital, so it would be the highest energy.

The next strongest would be between the ligands and the d xy and d xzbecause these orbitals have z components, but there is a node on the axis where the ligand lies. Only pi intereactions will be possible, which tend to be weaker than sigma. So they will lie below the d z2 in energy. Finally, the two orbitals with only x and y components will not interact with the ligands delta symmetry with respect to the ligandsso they will be the lowest. MO diagram. The first of these will mix with the metal p orbitals to make bonding and antibonding combinations, but neither of these will affect the frontier orbital region.

The second one has the proper symmetry to interact with d xz and d yz. The d xy and d x2-y2 will remain nonbonding.

Cobalt(II) chloride

The new diagram will look like this:. The sigma only version does not coincide with the ligand field diagram, but the sigma and pi version does.A complex is a substance in which a metal atom or ion is associated with a group of neutral molecules or anions called ligands.

Coordination compounds are neutral substances i. You will learn more about coordination compounds in the lab lectures of experiment 4 in this course. The coordination compounds are named in the following way. At the end of this tutorial we have some examples to show you how coordination compounds are named.

To name a coordination compound, no matter whether the complex ion is the cation or the anion, always name the cation before the anion.

This is just like naming an ionic compound.

Name the ligands first, in alphabetical order, then the metal atom or ion. Note: The metal atom or ion is written before the ligands in the chemical formula. Greek prefixes are used to designate the number of each type of ligand in the complex ion, e. If the ligand already contains a Greek prefix e.

See examples 3 and 4. The numerical prefixes are listed in Table 2. After naming the ligands, name the central metal. If the complex ion is a cation, the metal is named same as the element. For example, Co in a complex cation is call cobalt and Pt is called platinum. See examples See examples 5 and 6. For example, Co in a complex anion is called cobaltate and Pt is called platinate. For some metals, the Latin names are used in the complex anions e.

Fe is called ferrate not ironate. Following the name of the metal, the oxidation state of the metal in the complex is given as a Roman numeral in parentheses. To name a neutral complex molecule, follow the rules of naming a complex cation. See examples 7 and 8. For historic reasons, some coordination compounds are called by their common names.

Examples Give the systematic names for the following coordination compounds:. Answer: triamminetriaquachromium III chloride.

Solution: The complex ion is inside the parentheses, which is a cation. The ammine ligands are named before the aqua ligands according to alphabetical order. From the charge on the complex ion and the charge on the ligands, we can calculate the oxidation number of the metal.

Trick for the VBT - Valence Bond Theory - Coordination Compounds.

In this example, all the ligands are neutral molecules. Answer: pentaamminechloroplatinum IV bromide. Solution: The complex ion is a cation, the counter anion is the 3 bromides. The NH 3 are neutral molecules while the chloride carries - 1 charge. Answer: dichlorobis ethylenediamine platinum IV chloride.

Solution: ethylenediamine is a bidentate ligand, the bis- prefix is used instead of di. Solution: The sulfate is the counter anion in this molecule.

Again, remember that you never have to indicate the number of cations and anions in the name of an ionic compound. Solution: potassium is the cation and the complex ion is the anion.Cobalt III chloride or cobaltic chloride is an unstable and elusive compound of cobalt and chlorine with formula CoCl 3.

The compound has been reported to exist in the gas phase at high temperatures, in equilibrium with cobalt II chloride and chlorine gas [2] [3].

It has also been found to be stable at very low temperatures, dispersed in a frozen argon matrix. The infrared spectrum of the compound in frozen argon indicates that the isolated CoCl 3 molecule is planar with D 3h symmetry.

Thermodynamic properties for the gas phase have been determined by the Glushko Thermocenter of the Russian Academy of Sciences. The trichloride is formed through the equilibrium. At K below the melting point of CoCl 2Kthe trichloride was the predominant cobalt species in the vapor, with partial pressure of 0. However, equilibrium shifts to the left at higher temperatures.

At K, the partial pressures were 7. Cobalt trichloride, in amounts sufficient to study spectroscopically, was obtained by Green and others inby sputtering cobalt electrodes with chlorine atoms and trapping the resulting molecules in frozen argon at 14 K. In a report, the compound was claimed to arise in the electrolysis of cobalt II chloride in anhydrous ethanol. Trichlorides of cobalt III complexed with various ligands, such as organic aminescan be quite stable.
