How many possible structures exist for the tetrahedral complex [Zn(en)₃]²⁺?

Question

Quizplus · Accepted Answer

The complex has two different ligands, ethylenediamine (en) and sulfur (S). The ethylenediamine ligand has two nitrogen atoms, each of which can coordinate with the central metal ion (Zn). Therefore, there are two possible isomers based on the arrangement of the en ligands around the central metal ion. The S ligand can coordinate with the metal ion through either its sulfur atom or its lone pair of electrons, leading to two more possible isomers for each of the en isomers. Therefore, there are a total of four possible isomers for the tetrahedral complex.
