具有N…Cu作用的一维链状配合物Cu(C8H9N2O2)2的合成和晶体结构

The title complex Cu(L)₂ (HL=o-vanillin hydrazone) was synthesized by the reaction of Cu(CH₃COO)₂·H₂O with o-vanillin hydrazone in the ethanol. It was characterized by elemental analysis, IR and X-ray single crystal structure analysis. The crystal of the title complex [Cu(C₈H₉N₂O₂)₂] belongs to triclinic, space group P1 with a=0.457 57(8) nm, b=1.333 2(2) nm, c=1.386 0(3) nm, α=108.955(2)°, β=90.868(2)°, γ=95.859(2)°, V=0.794 4(2) nm³, Z=2, D_c=1.647 Mg·m^-3, μ=1.406 mm^-1, F(000)=406, and final R₁=0.035 1, wR₂=0.096 3. The complex comprises a four-coordinated copper(Ⅱ) center, with an N₂O₂ planar coordination environment. The molecules are packed in one-dimensional chain polymer though the N…Cu interaction from adjacent molecules, respectively. CCDC: 634854.
