摘要
A novel binucleus complex [Cd2（phen）4（adip）（NO3）2] （phen = phenanthroline, H2adip = adipic acid） has been synthesized by the reaction of phen and H2adip with cadmium（Ⅱ） salt. Elemental analysis, IR spectra and X-ray crystal structure analysis were carried out to determine the crystal structure of the title complex. The crystal belongs to triclinic, space group P1^- with a = 9.638（7）, b = 10.315（7）, c = 13.109（10） A, α = 88.305（11）, β = 69.011（11）, γ = 75.818（11）°, C27H20N5O5Cd, Mr = 606.88, Z = 2, V = 1177.2（14）A^3, Dc = 1.712 g/cm^3,μ= 0.979 mm^-1, -8≤h ≤11, -12≤k≤ 12, -10≤l≤ 15, F（000） = 610, Rint = 0.0314, R = 0.0739 and wR = 0.1922 （Ⅰ〉 2σ（Ⅰ）. The cadmium atom is seven-coordinated in a distorted pentagonal bipyramidal configuration. The complex forms a 2-D supramolecular framework by C-H…O weak interactions and π-π stacking of neighbouring phen ligands.
