The octahedral complex/complex ion which shows both facial and meridional isomers is

Question

The octahedral complex/complex ion which shows both facial and meridional isomers is (A) triglycinato cobalt (III) (B) tris (ethylene diamine) cobalt (III) (C) dichloro diglycinato cobalt (III) (D) trioxalate cobaltate (III)

Tardigrade Admin · Accepted Answer

Complexes of the type [M (a a)2 a2] show geometrical or fac-mer isomerism. (where, aa = bidentate ligand and a is monodentate ligand.) Among the given, dichlorodiglycinato cobalt (III), I.e., [C o C l2 (g l y)2] is such salt, so it will show fac and mer isomerism. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-qbzb0lfu7sxp.png" />

Q. The octahedral complex/complex ion which shows both facial and meridional isomers is

triglycinato cobalt (III)

tris (ethylene diamine) cobalt (III)

dichloro diglycinato cobalt (III)

trioxalate cobaltate (III)

Complexes of the type $[M (aa)_{2} a_{2}]$ show geometrical or fac-mer isomerism. (where, aa = bidentate ligand and a is monodentate ligand.) Among the given, dichlorodiglycinato cobalt (III), I.e., $[C o C l_{2} (g l y)_{2}]$ is such salt, so it will show fac and mer isomerism.
