以2-(4-甲基苯甲酰基)苯甲酸(HL)及2,2′-联吡啶(2,2′-bipy)为配体合成了一个双核铜(Ⅱ)配合物[Cu2(L)4(2,2′-bipy)2]·H2O(1),并对其进行了晶体结构测定。测定结果表明,该配合物晶体属于三斜晶系,空间群为P1,晶胞参数:a=1.012 57(15)nm,b=1.312 5(2)nm,c=1.317 0(2)nm,α=82.985(2)°,β=76.437(2)°,γ=88.290(2)°,V=1.688 7(4)nm3,Dc=1.391 g·cm-3,Z=2,F(000)=732,GooF=1.027,最终偏离因子R1=0.037 5,wR2=0.091 4。在配合物分子中相邻的2个铜(Ⅱ)离子通过2个2-(4-甲基苯甲酰基)苯甲酸根桥联配位连接起来,其端位各与1个2-(4-甲基苯甲酰基)苯甲酸根和1个2,2′-联吡啶分子配位,整个分子形成了双核结构。测定了标题配合物的荧光和磁性,结果表明:当激发波长为608 nm时,配合物在472和476 nm处有2个较强的荧光发射峰;在2~100 K,配合物具有顺磁性。
A binuclear copper (Ⅱ) complex [Cu2 (L)] 2 was synthesized from 2- (4-methylbenzoyl) benzoic acid (HL) and 2,2’-bipy ) 4 (2,2’-bipy) 2] · H2O (1) were synthesized and their crystal structures were determined. The results show that the crystal belongs to the triclinic system, the space group is P1 and the unit cell parameters are as follows: a = 1.012 57 (15) nm, b = 1.312 5 (2) nm, c = 1.317 0 α = 82.985 (2) °, β = 76.437 (2) °, γ = 88.290 (2) °, V = 1.688 7 (4) nm3 and Dc = 1.391 g · cm- = 732, GooF = 1.027, final deviation factor R1 = 0.037 5, wR2 = 0.091 4. The two adjacent copper (II) ions in the complex molecule are bridged by two 2- (4-methylbenzoyl) benzoate ligands and each end is connected with one 2- (4 - methylbenzoyl) benzoate and a 2,2’-dipyridyl molecule coordinate, the entire molecule to form a dual-core structure. The fluorescence and magnetic properties of the title complexes were determined. The results show that the complexes have two strong fluorescence emission peaks at 472 nm and 476 nm when the excitation wavelength is 608 nm. The complexes have paramagnetic .
