A complex of the type [M(AA)2X2]n+ is known to be optically active. What does this indicate about the structure of the complex? Give one example of such complex.
An optically active complex of the type [M(AA)2X2]n+ indicates cis-octahedral structure, e.g., cis−[Pt(en)2Cl2]2+ or cis−[Cr(en)2Cl2]+ because its mirror image isomers are non-superimposible.
