摘要 异金属桥联多核配合物由于具有独特性质而得到了广泛的研究^[1-3]。金属多核化合物化学已被应用于现代科学的许多学科,并且为化学、物理学和生物学之间的交叉渗透提供了广阔的发展空间^[4-6]。获得这些异金属体系最有效的方法是利用“配合物为配体”的合成方法。 one new complex,[Cu(aeop)Ni(dpt)(H2O)]·5H2O, [H4aeop=N′-(2-Aminoterephthalic acid)-N"-(1,3-Propanediamine) Oxamide], has been prepared by the diffusion method, where (aeop)^4- as bridging ligand, dpt as end ligand and characterized by elemental analysis, IR and X-ray crystal structure determination. It crystallizes in the Triclinic system, P^-1 space group with a=0.88592(4)nm, b=1.23253(6)nm, c=1.30124(6)nm, α=85.5930(10)°,β=78.7530(10)°, γ=89.382 0(10)°, V=1.38943(11) nm^3, Z=2. The crystal structure analysis shows that intermolecular O-H…O and N-H…O hydrogen bonds result in a 3D supermolecular construction. The complex was characterized by magnetic susceptibility and presents a antiferromagnetic interaction (J=-46.4 cm^-1, g=2.24).
