| Abstract: | In the crystal structure of the title compound, [Zn(C4H13N3)2]2[Fe(CN)6]·4H2O, the asymmetric unit is formed by a [Zn(dien)2]2+ cation (dien = diethylenetriamine, NH2CH2CH2NHCH2CH2NH2), water molecules and half of the [Fe(CN)6]4? anion which is related by inversion symmetry through the Fe atom. The geometry around the Zn and Fe atoms is distorted octahedral and octahedral, respectively. Intramolecular O—H?O hydrogen bonds involving the water molecules, and intermolecular O—H?N hydrogen bonds involving the water molecules and the anions, result in an infinite chain. Intramolecular O—H?O and N—H?N, and intermolecular O—H?N, N—H?O and N—H?N hydrogen bonds form a three‐dimensional framework. |
