NettetLigand isomerism is determined by the position isomer of the ligand. There are isomeric coordination compounds that have isomerism only within the ligand groups as the overall isomerism. This isomerism is a sort of isomerism that is unique. Diamino propane, for example, can have amine groups in either the terminal (1,3-) or 1,2-positions. NettetThis problem has been solved!
