199sn solid state nmr characterization of busno(oh)

Abstract

The119Sn MAS NMR characterization of butylstannonic acid, BuSnO(OH), clearly shows that more than 80% of its tin atoms are six-coordinate, the remaining 20% being five-coordinate. Even though a precise structure cannot be proposed, the119Sn NMR parameters indicate strong similarities between the six-coordinate tin atoms of BuSnO(OH) and those constituting the poles of the oxo-cluster {(BuSn)12O14(OH)6}2+. © 2002, by Walter de Gruyter GmbH & Co.
