| 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(Mo Kα)=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。 | |

| Abstract: Anew copper(Ⅱ) complex {[Cu2(Phen)4(NO3)][Cu(Phen)2(L)]2(L)2(NO3)3}·2H2O (1) with 2-benzoylbenzoic acid (HL) and 1,10-phenanthroline (Phen) as ligands has been synthesized. Crystal data for the complex are as follows: triclinic, space group P1, 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=1.408 g·cm-3, Z=1, μ(Mo Kα)=0.700 mm-1, F(000)=1480, final discrepancy factors R10.0571, wR2=0.1334. In 1, there are two mononuclear cations [Cu(Phen)2(L)]+ and one dinuclear cation [Cu2(Phen)4(NO3)]3+, and the four central Cu(Ⅱ) ions are all penta-coordinated. The electrochemical, fluorescent and magnetic properties of 1 were investigated. The results show that the electron transfer in the electrode reaction of 1 is quasi reversible, and the electrode reaction corresponds to Cu(Ⅱ)/Cu(Ⅰ). When the exciting radiation set at 488 nm, 1 can give off strong fluorescence band at around 494 nm. In addition, 1 displays diamagnetic property in temperatures range of 300~52 K. CCDC: 929034. | |
