摘要：

Three heterobinuclear complexes have been synthesized, namely [Cu(oxpn)Ni(L)2](ClO4)2·xH2O (L=2,2′-bipyridyl (bpy), 1,10-phenanthroline (phen), and 5-nitro-1,10-phenanthroline (NO2-phen)), where oxpn is N,N′-bis(3-aminopropyl)oxamido. The crystal structure of [Cu(oxpn)Ni(phen)2](ClO4)2·CH3OH·H2O has been determined. Crystal data: triclinic, space group P1, with a=9.661(3), b= 13.522(2), c=17.143(3) Å, α=86.39(2), β= 82.09(2) and γ=71.73(2)° at room temperature, Z=2. The copper(II) ion is in a square environment and the nickel(II) is in an octahedral environment. The dihedral angle between the two metal equatorial planes is 5.40°. The CuNi distance is 5.338 Å. The temperature dependence of the magnetic susceptibility of [Cu(oxpn)Ni(phen)2(ClO2)2·H2O has been studied, giving the exchange integral J=-47.22 cm-1. This indicates an antiferromagnetic interaction among the metal ions. © 1990.
