Abstract

RSn(OAmt)3 with R = n-butyl, n-butenyl or para-styryl, which are monomeric precursors, have been hydrolyzed. The so-obtained products have been characterized mainly by 119Sn NMR. In every cases, tin expands its coordination from 4 to 5 and 6, and hydrolysis yields tin oxo-hydroxo species of small size. For n-butyl and n-butenyl, a cage-like tin oxo-hydroxo cluster, {(RSn)12(μ3–O)14(μ2-OH)6}2+, was evidenced as the major compound formed. Organic polymerization of the unsaturated organic groups linked to tin was initiated on the hydrolysis products and yielded hybrid systems which can be pictured as tin oxo-hydroxo oligomers attached together by polymeric chains.
