Abstract
In the title compound, [Zn(C10H8N2)(C12H8N2)(H2O)2](NO3)2·0.5C10H8N2·H2O, the ZnII atom is coordinated in a distorted octahedral geometry by two N atoms from two 4,4′-bipyridine (4,4′-bipy) ligands, two N atoms from a chelating 1,10-phenanthroline ligand and two O atoms from two mutually cis water molecules. The 4,4′-bipy ligands bridge the ZnII atoms into a chain structure along [100]. The uncoordinated 4,4′-bipy molecule lies on an inversion center. O—H...O and O—H...N hydrogen bonds connect the cationic chains, the nitrate anions, the uncoordinated 4,4′-bipy molecules and the water molecules into tow-dimensional networks.
