Hz. Wang et al., SYNTHESIS AND STRUCTURE OF MU-TETRABUTYLA DIPAMIDE LANTHANIUM(III) BINUCLEAR COMPLEX )(4)CONBU(2)][BU(2)NCO(CH2)(4)CONBU(2)](2)(NO3)(6), Huaxue xuebao, 53(2), 1995, pp. 141-146
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.
