【 摘 要 】

The title complex, [Ni2(C9H4O6)2(C13H8N4)2(H2O)4]·2H2O, bis­(μ-5-carb­oxy­benzene-1,3-di­carboxyl­ato-κ2O1:O1′)bis­[di­aqua(1H-imidazo[4,5-f][1,10]phenanthroline-κ2N7,N8)nickel(II)] di­hydrate, 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]phenanthroline (IP). The crystal has triclinic (P-1) 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.
