Abstract

In the title complex, [Ni(C12H8N2)3](NO3)2·4H2O, the NiII ion is octahedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O—H⋯O and C—H⋯O hydrogen bonds are present between the complex cations, nitrate anions and water molecules. O—H⋯O hydrogen bonds between the uncoordinated water molecules lead to the formation of a four-membered ring water cluster, with a planar configuration. There were an additional five grossly disordered water molecules in the asymmetric unit, which were removed by the subroutine SQUEEZE; these were were excluded in the calculation of the molecular weight, etc. π–π stacking interactions between the aromatic rings are also observed [centroid–centroid distances = 3.697 (2), 3.728 (2) and 3.761 (2) Å].
