Question

For questions 5–7, determine the oxidation state of the metal in each of the following complexes. Draw ALL linkage isomers and stereoisomers for each complex CLEARLY showing enantiomers. Where possible, label each isomer as cis, trans, fac, mer, D and/or L. You must properly use shorthand notation for multidentate ligands. Note: do not consider the chirality of ligands. Be careful! Not all isomers can be labeled and you will lose credit for mislabeled as well as duplicate structures.

5. K[RuCl3(NH3)3]

6. Na[Nb(en)(ox)Cl2]

7. [YenF2(CO)2]Cl

Explanation / Answer

1) K[RuCl3(NH3)3]

The charge on the metal ion is "+3" since all other ligands are neutral molecules .Therefore the charge of he metal will be the same as the charge of the complex.

Oxidation state of K in the above complex = "+3"

2) Na[Nb(en)(ox)Cl2]

Na is the cation and the complex ion is the anion

oxidation state of metal(Na) in the compleax =+2

3)[YenF2(CO)2]Cl

oxidation sate of Cobalt(CO ) in the complex must be "+3"
