The total number of all possible isomers for the square planar complex with formula K [ M(NCS)(NO ₂ )(gly) ] is ____. ( M = metal ion and gly = NH ₂ CH ₂ COO ^- )

Step-by-step solution

The given complex is K [ M(NCS)(NO ₂ )(gly) ] . The complex anion is [ M(NCS)(NO ₂ )(gly) ]⁻ . The ligands present in the complex are: 1. gly ^- (glycinate): An unsymmetrical bidentate ligand coordinating through nitrogen (N) and oxygen (O). Let this be represented as (AB) . 2. NCS ^- : An ambidentate monodentate ligand that can coordinate through nitrogen ( -NCS ) or sulfur ( -SCN ). 3. NO ₂^- : An ambidentate monodentate ligand that can coordinate through nitrogen ( -NO ₂ ) or oxygen ( -ONO ). First, we find the
