摘要
将Ｇｌｙ－ＧｌｙＯ、４，４＇－联吡啶与Ｃｕ（ＮＯ_３）_２·Ｈ_２Ｏ在二次水溶液中反应，合成出以４，４＇－ｂｐｙ为中继基、Ｃｌｙ－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合物晶体的化学结构式为［（Ｈ_２ＮＣＨ_２ＣＯＮＨＣＨ_２ＣＯＯ）Ｃｕ（ＯＨ）（Ｃ_（１０）Ｈ_８Ｎ_２）Ｃｕ（ＯＮ）（Ｈ_２ＮＣＨ_２ＣＯＮＨＣＨ_２ＣＯＯ）］·９Ｈ_２Ｏ．晶体属Ｐ 空间群，晶胞参数ａ＝１．１４１２ｎｍ，ｂ＝１．２２９８ｎｍ，ｃ＝１．４２６９ｎｍ，α＝１１３．８２°，β＝１０１．９１°，γ＝１０３．６４°，Ｚ＝２．最终一致性因子Ｒ值为０．０６８，Ｒ_ｗ值为０．０５７，标准偏差σ＝０．１９５１。
A novel binuclear cupric complex with Gly-GlyO chelate ring and 4, 4'-dipyridyl as an intermediate radical was synthesized by the reaction of Gly-GlyO,4, 4'-dipyridyl and cupric nitrate in aqueous solution. The structural formula of the complex was confirmed as [(H_2NCH_2CONHCH_2COO)Cu(OH)(C_(10)H_8N_2)Cu(OH)(H_2NCH_2CONHCH_2COO)]·9H_2O by X-ray single-crystal structure analysis. Crystallographic data are as follows:a triclinic system with a space group,a=1. 1412 nm,b=1. 2298 nm,c=1. 4269 nm, a=113. 83°,β=101. 91°,γ=103. 64°, Z=2. The diffraction data were collected on a Nicolet XRS R3Diffractometer. The structural data were refined by the block matrix least squares program to final R value of 0. 068 and RW value of 0. 057.
