摘　　要：合成的标题配合物晶体属三斜晶系,空间群为P(?).晶胞参数:a=1.4693(2)、b=1.5882(3).c=1.9916(4)nm,α=90.92(2),β=92.93(1),γ=103.73(1)°“,V=4.507nm^3,D_c=1.29g. cm^(-3),Z=2.配合物为双核分子,一个配合物分了中有三个有机配体分子,其中一个有机配体以两个羰基分别连结两个La(Ⅲ),此外,每个 La(Ⅲ)各有一个有机配体和三个硝酸根配位,有机配体以两个羰基配位,三个硝酸根都是双齿配体,两个La(Ⅲ)The complex La2μ-[ Bu2NCO(CH2)4CONBu2] [Bu2NCO(CH2)4CONBu2]2(NO3)6 has been synthesized. The crystal structure of title complex was established by a single-crystal X-ray diffraction study and described as follows: triclinic space group P 1, a= 1.4693(2), b= 1.5882(3), c=1.9916(4)nm, α= 90.92(2), β=92.93(1),γ= 103.73(1)°, V=4.507(1)nm3, Dc=1.29g·cm-3, Final R value is 0.0738. This complex has binuclear molecule with three organic ligand molecules. Two carbonyls of one organic ligand join two La(Ⅲ), in addition each La(Ⅲ) is coordinated through two carbonyls of one organic ligand, six nitrates are all bidentate ligands. Each La(Ⅲ) is coordinated by nine oxygen atoms which form a distorted tricapped trigonal prism.
