Synthesis and characterization of nonaisopropoxodizirconatotin(IV) complexes

Abstract

A number of novel heteroleptic nonaisopropoxodizirconatotin(IV) complexes of the type [Sn{Zr₂(OPr<i>ⁱ</i>)₉}_nCl_4-n](where n= 1-3) have been synthesised by the reactions of SnCl₄ with KZr₂(OPr<i>ⁱ</i>)₉,in benzene in requisite (1:1, 1:2, or 1:3) molar ratios. Replacement of chloride in these derivatives by an appropriate alkoxide affords volatile, heterobimetallic derivatives of the type [Sn{Zr₂(OPr<i>ⁱ</i> )₉}_n(OR)_4-n] (R =Pr<i>ⁱ</i>, Bu<i>^t</i>, n = 2 or 3). These novel heterometal alkoxides have been characterized by elemental analyses, molecular weight measurements, IR and multinuclear (¹H, ¹³C and ¹¹⁹Sn) NMR spectral studies.
