26 A complex of the type M(AA)2X2n+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)2X2n+ indicates cis-octahedral structure,

eg. cis Pt(en2Cl22+  or cis-Cr(en)2Cl2+ because its minor image isomers are


Non-superimposable isomers of Pt(en)2Cl22+
