摘要： 采用Gly-Glyo,2,2'-联吡啶与Cu(NO3)2·H2O在二次水溶液中反应,合成了以Gly-Glyo作为中继基的新型双核配合物.经X射线单晶结构分析确定该配合物晶体的化学结构式[(C10H8N2)Cu(H2NCH2CONHCH2COO)Cu(C10H8N2)2](NO3)3.晶体属三斜晶系,P1空间群,晶胞参数:a=1.4268nm,b=1.1754nm,c=1.4059nm,α=104.01°,β=91.56°,γ=72.22°,Z=2.衍射数据在NicoletXRDR3型四圆衍射仪上收集,结构参数经块矩阵最小二乘法精修后,最终一致性因子R值为0.070.

Abstract: A novel binuclear complex with Gly-Glyo as a intermediate radical was synthesized by the raection of Gly-Glyo 2, 2'-dipyridyl and cupric nitrate in aqueous solution.The structural formula of complex was confirmed as {[(C10H8N2)Cu(H2NCH2CONHCH2COO)Cu(C10H8N2)2](NO3)3} by X-ray single-crystal structure analysis.Crystallographic parameters of the complex crystal are as follows, a triclinic system with space group P1,a=1.4268 nm,6=1.17542 nm, c=1.4059 nm, α= 104.01°,β=91.56°,γ=72.22°,V=2.17569 nm3, Z=2.Diffraction data were collected on a Nicolet XRD R3 Diffractometer.The crystal structure was refined by block matrix least squares program to final R value of 0.070.
