A complex of cobalt and copper (Cu (pn) 2Co2 (BTA) 4 (pn) 2] · 4H2O was synthesized and characterized by X-ray single crystal diffraction. The results show that the compound has a trinuclear structure and belongs to monoclinic system. The cell parameters of the P21 / n space group are as follows: a = 8.657 1 (2), b = 13.666 7 (3), c = 18.516 7 (3) , β = 100.783 0 (10) °, Mr = 1 154.47 , V = 2 152.10 (8) 3, Z = 2, Dc = 1.782 g · cm -3, μ = 1.343 mm -1, F (000) = 1 190.0, R = 0.044 4, wR = 0.107 9 > 2σ (I)) .In this compound, π-π interaction with OH ... N, NH ... N and OH ... O hydrogen bond to form a three-dimensional supramolecular structure through the coordination of the unit and the crystal water, and reported that the compound solution The fluorescent properties.
