摘要: 以2-苯甲酰苯甲酸(HL)和1,10-邻菲啰啉(Phen)为配体合成了一个新的铜(Ⅱ)配合物{[Cu2(Phen)4(NO3)][Cu(Phen)2(L)]2(L)2(NO3)3}·2H2O(1)。该化合物晶体属三斜晶系,空间群P1,晶胞参数:a=1.13857(5)nm,b=1.19349(7)nm,c=2.61531(13)nm,α=89.4280(10)°,β=82.753(2)°,γ=74.5370(10)°,V=3.3968(3)nm3,Dc=1.408g·cm-3,Z=1,μ(MoKα)=0.700mm-1,F(000)=1480,最终偏离因子R1=0.0571,wR2=0.1334。在标题配合物分子中,有2个单核阳离子[Cu(Phen)2(L)]+和1个双核阳离子[Cu2(Phen)4(NO3)]3+,中心铜(Ⅱ)离子的配位数都是五。测定了标题配合物的电化学、荧光和磁性。结果表明:在循环伏安过程中,配合物的电子转移是准可逆的,对应的电极反应是Cu(Ⅱ)/Cu(Ⅰ);当激发波长为488nm时,配合物在494nm附近有较强的荧光发射峰;在300~52K,配合物具有抗磁性。
