摘要
新制备的Cu2(C5H5N)2(C8H7O2)4加入到溶有2-甲基苯甲酸、吡啶的C2H5OH/H2O(1∶1,v/v)混合溶剂中反应,得到新的双核铜配合物Cu2(C5H5N)2(C8H7O2)4晶体,结构经X-衍射法表征.晶体结构中,四个苯甲酸离子羧基八个O原子经syn-syn式桥连二个Cu原子成灯笼状,在轴向分别由二个吡啶分子N配位而形成四方锥形几何结构.分子间沿(010)方向,形成折叠假性的六边形紧密堆积结构.配合物CCDC号:856726.
Reactions of thefreshly prepared Cu（OH）2·y H2O precipitate, 2 -methyl benzoic acid with pyridinein C2H5 OH/H2 O （ 1 ： 1, v/v） afforded Cu2 （C5H5 N）2 （C8 H7O2 ） 4 （ 1 ）. Thecentrosymmetric binuclear compound was structurally characterized by X- ray diffraction methods. In the crystal,four 2 -methyl benzoate anions form a cage around two Cu atoms in a syn -syn configuration, two pyridine molecules are apically bonded to the Cu atoms, which show a square - pyramidal coordination geometry. The molecular packing forms a puckered pseudo - hexagonal close- packed framework in （010）. CCDC：856726.
