Q. Describe Coordinated octahedral complexes?
Six-coordinated octahedral complexes of the type Mubr, Ma3b3, Ma3b2c, Ma3bcd, Ma2bcd, Ma2bcde, Mabcd of would all give geometrical isomers. Systems with one or two bidentate ligands and rest monodentate would also give geometrical isomers. Thus we-see that with this geometry a large number of isomers are possible whether they can be isolated or separated is a different question which depends on so many factors. As we increase the number of different ligands, the possible number of isomers increases. For example, Mub2
type of complex would give only two isomers cis- and trans-. Similarly for Ma3b3 type of complex we again get two isomers facial (fac-) and meridional (mer-) isomers. In the former (fac-) three ligands of one type form one triangular face of the octahedron and the other three on the opposite face, Fig. (a). In the latter (mer-). one set of these ligands art arranged around an edge of the octahedron whereas the other set occupies the opposite edge as shown in Fig.(b).
