Question

Coordination number of pt in diamminedichloroplatinum(ii)

Answer 1

Platinum is bonded with two types of ligands,

Ethylenediamine which is bidentate ligand is of two in number hence 2X2 =4

Chloride which is an unindented ligand is of two in number hence 1 X 2 = 2

Hence co-ordination number of Platinum will be 4 + 2 = 6

Oxidation state of Pt:

Charge on complex = 0

Hence, [x + (0 X 2) + ( -1 X 2)] = 0

x + 0 -2 = 0

x = 2

Hence oxidation state of Pt in the complex is +2
