metal-organic compounds
The title complex, {[Zn(C8H3NO6)(H2O)3]·H2O}n, has a one-dimensional chain structure. The two carboxylate groups of the dianionic 2-nitroterephthalate ligand adopt mono- and bidentate chelating modes. The Zn atom shows distorted octahedral coordination, bonded to three O atoms from two carboxylate groups and three O atoms of three non-equivalent coordinated water molecules. The one-dimensional chains are aggregated into two-dimensional layers through inter-chain hydrogen bonding. The whole three-dimensional structure is further stabilized by inter-layer hydrogen bonds.

In the title complex, [Zn(C8H3NO6)(H2O)3]n, the two carboxylate groups of the 4-nitrophthalate dianion ligands have monodentate and 1,3-bridging modes, and Zn atoms are interconnected by three O atoms from the two carboxylate groups into a zigzag one-dimensional chain along the b-axis direction. The Zn atom shows distorted octahedral coordination as it is bonded to three O atoms from carboxylate groups of three 4-nitrophthalate ligands and to three O atoms of three non-equivalent coordinated water molecules. The one-dimensional chains are aggregated into two-dimensional layers through inter-chain hydrogen bonding. The whole three-dimensional structure is further maintained and stabilized by inter-layer hydrogen bonds.
