$\left[Co(NO_2)_3(NH_3)_3\right]$

Vedclass · Answer

(B) neutral complex is one where the coordination sphere carries no net charge.In $\left[Co(NO_2)_3(NH_3)_3ight]$,the oxidation state of $Co$ is $+3$,and the ligands are $3 	imes NO_2^-$ $(-3)$ and $3 	imes NH_3$ $(0)$. The total charge is $(+3) + (-3) + (0) = 0$.Therefore,$\left[Co(NO_2)_3(NH_3)_3ight]$ is a neutral complex.$\left[Co(H_2O)(NH_3)_5ight]I_3$ and $\left[Fe(H_2O)_3(NCS)ight]Cl_2$ are cationic complexes,while $Na\left[Co(NO_2)_6ight]$ is an anionic complex.

Which among the following complexes is a neutral complex?
