摘要：

<正> The title complex [ErY（Gly）6（H2O）4]（ClO4）6·51H2O has been synthesized.Its crystal structure has beendetermined by X-ray diffraction method.The crystal is triclinic with space group P.The unit cell parametersare as follows:a=1.1518（4） nm,b=1.4105（7） nm,c=1.5530（6） nm,α=96.61（3）°,β=102.74（3）°,γ=105.70（3）°,V=2.3277（17） nm3,Z=2,Dcalc=2.091 g/cm3.The structure has been refined to a final R of0.0785.The crystal-is an infinite chain complex,in which four carboxyl groups from glycine molecules bridge theEr3+ and Y3+ ions,and the other two carboxyl groups bridge two adjacent Er3+ or Y3+ ions.
