| Popis: | In the title polymeric complex, {[Zn(C24H22N6O2)(H2O)4](NO3)2·2H2O}n, the ZnII cation, located about a twofold rotation axis, is coordinated by two imidazole groups and four water molecules in a distorted N2O4 octahedral geometry; among the four coordinate water molecules, two are located on the same twofold rotation axis. The 1,4-bis[4-(1H-imidazol-1-yl)benzoyl]piperazine] ligand is centro-symmetric, with the centroid of the piperazine ring located on an inversion center, and bridges the ZnII cations, forming polymeric chains propagating along [201]. In the crystal, O—H...O and weak C—H...O hydrogen bonds link the polymeric chains, nitrate anions and solvent water molecules into a three-dimensional supramolecular architecture. A short O...O contact of 2.823 (13) Å is observed between neighboring nitrate anions. |
