Question

What kind of isomerism exists between [Cr(H2O)6]Cl3 (violet) and [Cr(H2O )5Cl]Cl2⋅ H2O (greyish-green)? (A) Linkage isomerism (B) Solvate isomerism (C) Ionisation isomerism (D) Coordination isomerism

Tardigrade Admin · Accepted Answer

This form of isomerism is known as 'hydrate isomerism' in case where water is involved as a solvent. This is similar to ionisation isomerism. Solvate isomers differ by whether or not a solvent molecule is directly bonded to the metal ion or merely present as free solvent molecules in the crystal lattice.
