24. Transition Metals and Coordination Compounds

Provide the complex ion structure when Cu⁺ combines with 2 hydroxide ions and 2 cyanide ions.

Provide the complex ion structure when a Cobalt (IV) ion combines with 2 chloride anions and 2 water molecules.

The molecule dimethylphosphinoethane [(CH₃)₂PCH₂CH₂P(CH₃)₂, which is abbreviated dmpe] is used as a ligand for some complexes that serve as catalysts. A complex that contains this ligand is Mo(CO)₄(dmpe) .

a. Draw the Lewis structure for dmpe, and compare it with ethylenediamine as a coordinating ligand.

b. What is the oxidation state of Mo in Na₂[Mo(CN)₂(CO)₂(dmpe)] ?

c. Sketch the structure of the [Mo(CN)₂(CO)₂(dmpe)]^2- ion, including all the possible isomers.
