G. Garg et al., SYNTHESIS AND CHARACTERIZATION OF NOVEL HOMOLEPTIC AND HETEROLEPTIC NONAISOPROPOXODIZIRCONATOSAMARIUM(III) COMPLEXES, Polyhedron, 12(11), 1993, pp. 1399-1402
Heterobimetallic isopropoxide derivatives of samarium(III) of the type
s [Cl3-nSm{Zr2(OPri)9}n] (n = 1, 2 or 3) have been prepared by the int
eraction Of SMCl3. 3PriOH with K(Zr2(OPri)9} in the desired molar (I :
1, 1: 2 or 1: 3) ratios in benzene. Chloride-isopropoxo (or tetraisop
ropoxoaluminato) exchange reactions have led to the formation of inter
esting hetero-(bi- or tri-) metal isopropoxides of samarium(III), L3-.
SM{Zr2(OPri)9}n [L = OPri, n = 1 or 2; L = Al(OPri)4, n = 1]. All thes
e products have been characterized by elemental analyses and spectrosc
opic (IR, NMR) studies.
