合成了2 个以1 ,1 ,2 ,2四乙酰基乙烷阴离子( T A E2 - ) 为桥联的双核铜配合物[(bipy Cu)(bipy Cu H2 O) T A E]( Cl O4)2 ·2 H2 O( Ⅰ) 和(bipy Cu)2 T A E( P F6)2 ·3 H2 O( Ⅱ) 及1 个多核铜配合物[ Cu T A E·2 H2 O]n( Ⅲ) ,并进行了表征。对配合物( Ⅰ) 进行了 X射线晶体结构分析,该配合物属于单斜晶系,空间群为 P21/ n ,晶胞参数为a = 7 .923(1) .465(5) 〓, b = 16 .068(3) 〓, c = 30 .182(7) 〓, β= 93 .18(2)°,晶胞体积 V= 3836 .5(12) 〓3 , Z= 4 , 最终偏离因子 R1 = 0 .1135 ,w R2 = 0 .3121 。磁性质研究表明在这两个双核铜配合物中两个金属铜之间存在弱的反铁磁性相互作用。
Two bipyridyl copper complexes (bipy-Cu H 2 O) T A E] bridged with 1, 1, 2, 2-tetraacetyl acetylene anion (T A E2 -) Cl O4) 2 · 2 H 2 O (I) and (bipy Cu) 2 T A E (P F6) 2 · 3 H 2 O (Ⅱ) and one multinuclear copper complex [Cu T A E · 2 H 2 O] n (Ⅲ), and characterized. X-ray crystallographic analysis of the complex (Ⅰ) shows that the complex belongs to the monoclinic system with a space group of P21 / n and a unit cell parameter of a = 7. 923 (1). 465 (5) 〓, b = 16. 068 (3) 〓, c = 30. 182 (7) 〓, β = 93. 18 (2) °, unit cell volume V = 3836. 5 (12) 〓 3, Z = 4, the final deviation factor R1 = 0. 1135, w R2 = 0. 3121. Magnetic properties show that there is a weak antiferromagnetic interaction between the two metallic copper in the two binuclear copper complexes.
