| Abstract: The preparation and crystal structure of title compound arc reported. The structural determination was carried out on a RASA-IIS(RIGAKU)diffratomctcr with X-ray intensity data collected in 3°<20<52° . The space group is P1 with a=6.712(3)Å,b=9.110(6)Å ,c=11.607(8)Å, α=70.17(5)° ,β=88.80(5)° ,γ=69.04(5)° ,Z=2. the structure was solved by Patterson method and refined with a full matrix least-squares procedure to R=0.076. Each Gd(Ⅲ)ion is coordinated with ten oxygen atoms from three nitrate groups and four water molcculers, forming a distorted icosahcdron. |
