According to the molar ratio of 1: 1, the copper complex KCuL in methanol and the CaCl2 aqueous solution were slowly diffused in the test tube to obtain the heteropolymetallic coordination polymer with 1D chain structure. The chemical composition was {[(CuL ) CH3CH2OH.0.5CH3OH} n, (H3L = N- (2 - {[(1E) - (5-chloro-2- hydroxyphenyl) methylene] amino} ethyl) 2-hydroxybenzamide) .It was characterized by IR spectrum and elemental analysis, and its crystal structure was determined by X-ray single crystal diffraction method. The crystal belongs to triclinic system, space group Pī, Cell parameters a = 1.22428 (18) nm, b = 1.30262 (19) nm, c = 1.427 1 (2) nm, α = 113.146 (2) °, β = 108.114 (2) °, , V = 1.9053 (5) nm3, C33.5H29Cl2Cu2CaN4O7, Mr = 860.725, Z = 2, Dc = 1.411 g / cm3, μ (MoK) α = 1.435 mm-1, F (000) = 824, wR = 0.2010, (I> 2σ (I)), 9616 observable diffraction points and 6544 independent diffraction points. The structural analysis shows that this compound is a coordination polymer with chain structure Things.
