Question

Coordination number of $Cr$ in $\left[Cr\right(gly{)}_2(H_{2}O{)}_2{]}^{+}$ is :

• A. 10
• B. 4
• C. 6
• D. 8

Answer 1

The correct option is C 6

Gylcinate $\left(gl{y}^{-}\right)$ is bidentate ligand and $H_{2}O$ is monodentate ligand.
There are 2 bidentate and 2 monodentate ligand. Thus, the coordination number of $Cr$ in $\left[Cr\right(gly{)}_2(H_{2}O{)}_2{]}^{+}$ is 6.
