| Popis: | In the title coordination polymer, {[Zn(C8H5NO4)(C3H4N2)]·0.25H2O}n, the Zn2+ cation has an N2O2 donor set involving two carboxylate O atoms from two 5-aminoisophthalate anions, one N atom from a 5-aminoisophthalate anion, and one imidazole N atom displaying a slightly distorted tetrahedral geometry with two additional O-atom neighbours, with Zn-to-ligand distances of 2.711 (2) and 2.717 (2) Å, respectively. Each 5-aminoisophthalate anion acts as a μ3-bridge linking symmetry-related ZnII ions into a layered polymeric structure parallel to (100). The asymmetric unit also comprises a disordered crystal water molecule located on an inversion centre with 0.25 occupancy. In the crystal, N—H...O hydrogen bonds form a three-dimensional network. |
