Synthesis and magnetism of copper(II) complexes with N,N'-1,2-propanedisalicylamidato-cuprate(II)

Abstract

Cu(sampn)NiL2 were synthesized (H4sampn = N, N'-1,2-propanedisalicylamide; L = 2,2'-bipyridyl, 1,10-phenanthroline). Based on elemental analyses, IR, and electronic spectra, the complexes probably have PhO-bridged structure and consist of Cu(II) in a planar environment and Ni(II) in a distorted octahedron. The complexes were characterized with variable-temp. magnetic susceptibility (4-300 K) and the data are least-squares fit to a susceptibility equation derived from spin Hamilton, H = 2JS1S2. The exchange integral, J, is -1.90 (bpy) and -1.68 (phen) cm-1 indicating that weak antiferromagnetic spin exchange interaction operates between both metal ions.
