Abstract

The title complex, [Ni2(C9H4O6)2(C13H8N4)2(H2O)4]·2H2O, bis(μ-5-carboxybenzene-1,3-dicarboxylato-κ2O1:O′) bis[diaqua-(1 H-imidazo[4,5-f][1,10]phenanthroline-κ2N7,N8) nickel(II)] di-hydrate, was obtained under solvothermal conditions by the reaction of benzene-1,3,5-tricarboxylic acid (H3BTC) with Ni(NO3)2 in the presence of 1H-imidazo[4,5-f][1,10]phenan-throline (IP). The crystal has triclinic (P1) symmetry with a centrosymmetric binuclear nickel(II) cluster. The NiII atom is coordinated by two N atoms from a chelating 1H-imidazo-[4,5-f][1,10]phenanthroline ligand, two carboxylate O atoms from two 5-carboxybenzene-1,3-dicarboxylate ligands and two water molecules in a slightly distorted octahedral geometry. Two carboxylate groups bridge two NiII cations, forming the binuclear complex. Extensive N - H⋯O, O - H⋯O and O - H⋯N hydrogen bonding is present in the crystal structure, forming a three-dimensional supermolecular framework. Weak π-π stacking is observed between parallel HBTC2- and IP ring systems, the face-to-face separation being 3.695 (2) Å.
