Abstract: In the title compound, [Cd(C₄H₅N₃)₂(H₂O)₄](ClO₄)₂·4C₄H₅N₃, the Cd^II atom (site symmetry ) is coordinated by two N-heterocycles and four water molecules, resulting in a distorted trans-CdN₂O₄ octahedral geometry for the metal. In the crystal, the cation, anion and free N-heterocycle molecules are linked by N-HN, N-HO, O-HN and O-HO hydrogen bonds, forming a three-dimensional network.
