If CO ligands are substituted by NO in respective neutral carbonyl compounds then which of the following will not be correct formula?

A

`Cr(CO)_(3)(NO)_(2)`

B

`Fe(CO)_(2)(NO)_(2)`

C

`Cr(NO)_(4)`

D

`Ni(CO)_(2)(NO)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Ligand NO is `3e^(-)` donar hence three CO ligands can be substituted by two NO ligands.
