A molecule or an ion which has only one donor atom to form one coordinate bond with the central metal atom is called unidentate ligand, e. A molecule or ion which contains two donor atoms and hence forms two coordinate bonds with the central metal atom is called adidentate A molecule or an ion which contains two donor atoms but only one of them forms a coordinate bond at a time with the central metal atom is called.

NCERT Solutions class 12 Chemistry Coordination Compounds part 1

Coordination compounds exhibit stereo isomerism and structural isomerism. Two types of stereoisomerism and their examples are as follows. These are obtained by keeping the position of one of the ligand, say NH3 fixed and rotating the positions of others. This type of isomers do not show any optical isomerism. Optical isomerism only rarely occurs in square planar or tetrahedral complexes and that too when they contain unsymmetrical chelating ligand.
