摘　　要：合成了以４，４′－ｂｐｙ为中继基、Ｇｌｙ－ＧｌｙＯ为螯环的新型双核铜配合物．经Ｘ射线单晶结构分析确定该配位化合物晶体的化学式为［（Ｈ２ＮＣＨ２ＣＯＮＨＣＨ２ＣＯＯ）Ｃｕ（ＯＨ）（Ｃ１０Ｈ８Ｎ２）Ｃｕ（ＯＨ）－（Ｈ２ＮＣＨ２ＣＯＮＨＣＨ２ＣＯＯ）］·１０Ｈ２Ｏ．晶体属三斜晶系，Ｐ１空间群，晶胞参数ａ＝０．７１２４（２）ｎｍ，ｂ＝１．１４０５（１０）ｎｍ，ｃ＝１．１４３４（１０）ｎｍ，α＝６７．５５°，β＝７９．０２°，γ＝７７．９７°，Ｖ＝０．８３４（３）ｎｍ３，Ｚ＝１．最终一致性因子Ｒ为０．０７２７．A novel binuclear cupric complex with Gly GlyO chelate ring and 4,4′ dipyridyl as an intermediate radical was synthesized by the reaction of 4,4′ dipy ridyl and cupric nitrate in aqueous solution. The structural formula of the complex was confirmed as [(H 2NCH 2CONHCH 2COO)(C 10 H 8N 2)Cu(OH)(H 2NCH 2CONHCH 2COO)]·10H 2O by X ray single crystal structure analysis. Crystallographic data are as follows: a triclinic system with a space group P 1, a =0 712 4(2) nm, b =1 140 5(1) nm, c =1 143 4(1) nm, α=67 65°, β=79 02° , γ=77 97° , V =0 834(3) nm 3, Z =1. The structural data were refined by the block matrix least squares program to final R value of 0 072 7.
