data and the crystal structure of [Ru(bpy)2(cept)]PF6·H2O (2) indicate that the coordination of the Hcpt− and cept− occurs via N1 of the triazole ring. The crystals of 2 are monoclinic and belong to the space group P21/n with a = 12.339(7), b = 16.512(7), c = 16.802(8) A, β = 110.29(4)°, and Z = 4. A water molecule is hydrogen-bonded to the carbonyl oxygen atom of the ethoxycarbonyl group with an O···O
两种新型 [Ru(bpy)2(L-L')]n+ 配合物与 L-L' = 3-carboxy-5-(pyrid-2'-yl)-1,2,4triazole (H2cpt) 的合成和性质) 或 3-(乙氧羰基)-5-(吡啶-2'-基)-1,2,4-三唑 (Hcept) 配体进行了描述。先前关于含有 (pyrid-2'-yl)-1,2,4-三唑的 RuII 配合物的出版物表明,它们的配位可能通过三唑环的 N1 和 N4 进行。[Ru(bpy)2(cept)]PF6·H2O (2) 的 1H NMR 光谱数据和晶体结构表明 Hcpt- 和 cept- 的配位通过三唑环的 N1 发生。2的晶体为单斜晶系,属于空间群P21/n,a = 12.339(7), b = 16.512(7), c = 16.802(8) A, β = 110.29(4)°, Z = 4 . 一个水分子与乙氧羰基的羰基氧原子氢键合,O···O距离为2
