| 摘要: 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=1.01257（15）nm，b=1.3125（2）nm，c=1.3170（2）nm，α=82.985（2）°，β=76.437（2）°，γ=88.290（2）°，V=1.6887（4）nm3，Dc=1.391g·cm-3，Z=2，F（000）=732，GooF=1.027，最终偏离因子R1=0.0375，wR2=0.0914。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608nm时，配合物在472和476nm处有2个较强的荧光发射峰；在2~100K，配合物具有顺磁性。 |

| Abstract: Anew dinuclear copper(Ⅱ) complex [Cu2(L)4(2,2'-bipy)2]·H2O (1) has been synthesized with 2-(4-methylbenzoyl)benzoic acid (HL) and 2,2'-bipyridine (2,2'-bipy) as ligands. Its crystal belongs to a triclinic system with space group P1, a=1.01257(15) nm, b=1.3125(2) nm, c=1.3170(2) nm, α=82.985(2)°, β=76.437(2)°, γ=88.290(2)°, V=1.6887(4) nm3, Dc=1.391 g·cm-3, Z=2, F(000)=732, GooF=1.027. Final R1=0.0375, wR2=0.0914. The crystal structure shows that two neighboring copper(Ⅱ) ions are linked together by two bridging2-(4-methylbenzoyl)benzoic acid anions, and their each end position coordinates with one 2-(4-methylbenzoyl)benzoic acid anion and one 2,2'-bipyridine molecule, forming a dinuclear structure. The fluorescent and magnetic properties of the title complex were discussed. The results show that the title complex has two emission bands at 472 and 476 nm, respectively, with the best excitation wavelength at 608 nm, and it is a paramagnetism system in temperatures range of 2~100 K. CCDC: 918797. |
