The complex La2m-[Bu2NCO(CH2)4CONBu2][Bu2NCO(CH2)4CONBu2]2(NO3)6 was synthesized. The crystal structure of title complex was established by a single-crystal x-ray diffraction study and described as follows: triclinic space group P1, a 1.4693(2), b 1.5882(3), c 1.9916(4) nm, a 90.92(2), b 92.93(1), g 103.73(1)? dc = 1.29 g cm-3, final R value is 0.0738. This complex has binuclear mol. with three organic ligand mols. Two carbonyls of one organic ligand join two La(III), in addition each La(III) is coordinated through two carbonyls to one organic ligand; the six nitrates are all bidentate ligands. Each La(III) is coordinated by nine O atoms which form a distorted tricapped trigonal prism.
