Question

What will unidentate ligands $\mathrm{A}$ and $\mathrm{X}$ give in a complex ${\mathrm{MA}}_3{\mathrm{X}}_3$?

Answer 1

Geometrical Isomerism in Coordination complexes:

• The coordination complexes having octahedral geometry also exhibit geometrical isomerism.
• They can exhibit cis/trans or fac/mer isomerism depending upon their formula.

In ${\mathrm{MA}}_3{\mathrm{X}}_3$ type complexes:

• The ${\mathrm{MA}}_3{\mathrm{X}}_3$ type complexes exhibit two geometrical isomers, i.e., Facial and Meridional isomers.
