摘要： 合成了2个异桥双铜配合物:[Cu2(pfhmp)Br]·2H2O(1)和[Cu2(pfhmp)C3H3N2]·2H2O(2),经元素分析、红外及摩尔电导等手段推知两配合物均为烯醇式构型.变温磁化率测定结果表明,由于外源桥的影响,铜离子间的反铁磁相互作用有明显差别.

Abstract: Two dicopper complexes containing different exogenous bridges, Cu2(pfhmp)Br ·2H2O(1) and Cu2(pfhmp)C3H3N2 · 2H2O(2), were synthesized, where pfhmp3- denotes dehy-drogen anion of N,N-diisonicotinoyl-hydroxy-4-methylisophthalaldehyde dihydrozone.Based on the elementary analysis, IRand molar conductance, the complexes are proposed to have hetero-bridged structures and enolic configuration.The determination of variable-temperature magnetic susceptibility indicates that the variation of exogenous bridge obviously changes magnetic exchanges interaction between two Cu(Ⅱ) ions.
