摘要
合成了2个含不同外源桥基的双铜配合物[Cu_2(pfhmp)OH]·2H_2O和[Cu_2(pfhmp)N_3]·H_2O,pfhmp^(3-)表明N,N′-二异烟酰基-2-羧基-4-甲基-1,3-苯二甲醛双腙的脱氢阴离子。经元素分析、红外光谱、摩尔电导等手段推知两配合物均为异桥结构与烯醇式构型,变温磁化率测定表明改变外源桥基会明显改变2个铜离子之间的磁交换作用。
Two dicopper complexes containing different exogenous bridges, Cu2(pfhmp)OH · 2H2O and Cu2(pfhmp)N3 · H2O, were synthesized, where pfhmp3- denotes dehydrogen anion of N,N-diisonicotinoyl-2-hydroxy-4-methylisophthalaldehyde dihydrozone. Based on elemental analysis , IR and molar conductance, the complexes are proposed to have hetergeneous bridged structures and enolic configuration. The determination of variable-temperature magnetic susceptibility indicates that the variation of exogenous bridge obviously changes magnetic exchange interaction between two Cu(Ⅱ ) ions.
