Triaqua(1,10-phenanthroline-κ2N,N′)(sulfato-κO)zinc(II)

The Zn(II) atom in the title compound, [Zn(SO4)(C12H8N2)(H2O)3], is coordinated by one O atom from a sulfate dianion, two N atoms from a 1,10-phenanthroline molecule and three water O atoms in an octahedral geometry. An intramolecular O—H...O hydrogen bond occurs. Intermolecular O—H...O hydrogen bonds generate a layer structure parallel to (001). There are weak C—H...O interactions within the layers.
