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=1.4268 nm,b=1.1754 nm,c=1.4059 nm,α=104.01°,β=91.56°,γ=72.22°,Z=2.衍射数据在Nicolet XRD R3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.

Gly-Glyo, 2,2’-dipyridyl and Cu (NO3) 2 · H2O were reacted in aqueous solution to synthesize a novel dinuclear complex with Gly-Glyo as a relay. The crystal is a triclinic system with P1 space group and unit cell parameters: a = 1.4268 nm, b = 1.1754 nm, c = 1.4059 nm, α = 104.01 °, β = 91.56 °, γ = 72.22 °, Z = 2. The diffraction data were collected on a Nicolet XRD R3 four-circular diffractometer and the structure parameters were refined by block matrix least- After the final consistency factor R value of 0.070.
