Abstract
Novel heterometallic isopropoxides of the lanthanides(III) and yttrium(III) with the formula [LnCl 3− x {Sn 2(OPr i) 9} x ] (Ln La, Pr, Nd, Lu and Y ; x = 2 or 3) have been synthesized by the reactions of LnCl 3 · 2Pr iOH with KSn 2(OPr i) 9 in 1 : 2 and 1 : 3 molar ratio in benzene. These complexes have been characterized by elemental analyses, isopropoxy proup estimations and molecular weight measurements. Their spectral [IR, electronic, multinuclear ( 1H, 13C, 119Sn) NMR] properties have been studied and discussed.
