A new complex [Ni (H2O) 6] [Ni2 (phen) 2 (BTC) 2 (H2O) 4] 4H2O (phen = orthophenanthroline; BTC = trimellitic acid) The crystal structure belongs to the triclinic system with the space group of P-1 and the unit cell parameter a = 0.84038, which is characterized by X-ray single crystal diffraction structure analysis and elemental analysis, infrared spectrum and the like. (7) nm, b = 0.92048 (8) nm, c = 1.64793 (14) nm, α = 97.3850 (10) °, β = 102.7930 (10) °, γ = 104.9700 ) nm3, F (000) = 622, Z = 1. The asymmetric structure of the title compound consists of NiO6 units and one dimer of Ni2N4O12 units which pass two orthophenrol and two Phthalic acid molecules form an eight-membered ring, and hydrogen bonds two independent structural units into a three-dimensional structure.
