Ps. Mansingh et al., SYNTHESIS AND CHARACTERIZATION OF DIOXOURANIUM(VI) AND THORIUM(IV) COMPLEXES OF 2-(2'-HYDROXYPHENYL)BENZIMIDAZOLE AND 2-(2'-PYRIDYL)-BENZOXAZOLE, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 35(6), 1996, pp. 479-482
The bidentate ligand 2-(2'-hydroxyphenyl)benzimidazole (L). forms mono
nuclear complexes of the type UO(2)L(2)X(2) (X=Cl, I, NCS, NO3, CH3COO
, 0.5 SO4) and ThL(2)X(4) (X=I, NCS, NO3), whereas the biheterocyclic
bidentate ligand 2-(2'-pyridyl)benzoxazole (L') forms complexes of the
type UO(2)L'X(2) (X=Cl, NCS, NO3, CH3COO, 0.5 SO4) and ThL'(2)X(4) (X
=NCS, NO3). The complexes are characterized by elemental analyses, con
ductivity and thermogravimetric measurements and IR as well as H-1 and
C-13 NMR spectral studies.
