SYNTHESIS AND STRUCTURE OF MU-TETRABUTYLA DIPAMIDE LANTHANIUM(III) BINUCLEAR COMPLEX )(4)CONBU(2)][BU(2)NCO(CH2)(4)CONBU(2)](2)(NO3)(6)

The complex La-2 H2)(4)CONBu(2)][Bu(2)NCO(CH2)(4)CONBu(2)](2)(NO3)( )6 has been synthesized. The crystal structure of title complex was esta blished by a single-crystal X-ray diffraction study and described as f ollows: triclinic space group P ($) over bar 1, a = 1.4693(2), b = 1.5 882(3), c = 1.9916(4)nm, alpha = 90.92(2), beta = 92.93(1), gamma = 10 3.73(1)degrees, V = 4.507(1)nm(3), D-c = 1.29g . cm(-3), Final R value is 0.0738. This complex has binuclear molecule with three organic lig and molecules. Two carbonyls of one organic ligand join two La (III), in addition each La(III) is coordinated through two carbonyls of one o rganic ligand, six nitrates are all bidentate ligands. Each La(III) is coordinated by nine oxygen atoms which form a distorted tricapped tri gonal prism.
