Abstract: New metal complexes of [Cu(sampn)CuL] type were synthesized, where sampn^4- denotes N,N'-1,2-propanedisalicylamidate anion and Ldenotes 2,2'-bipyridyl(bpy) or 1,10-phenanthroline(phen). Based on IR, elemental analyses and electronic spectra, the complexes are proposed to have phenoxy-bridged structure and to consist of the Cu(Ⅱ) in distorted planar environment. The complexes have been characterized with variable-temperature magnetic susceptibility (77～300K)and the observed data were fit to those from a modified Bleaney-Bowers equation by means of least-squares, resulting in a larger θ. This suggests that two binuclear units have a considerable intermolecular interaction.
