The sum of coordination number and oxidation number of the metal M in the complex [M(en)2(C2O4)]Cl (where, en is ethylenediamine) is
9
Given complex compound is [M(en)2(C2O4)]Cl
Let oxidation number of M is x.
∴ x - 2 - 2 = - 1
or x = + 3
Now, as coordination number is defined as the total number of binding sites attached to the metal. Hence, in the given complex coordination number is 6.
