Tin organometallic compounds: Classification and analysis of crystallographic and structural data: Part 1. Monomeric derivatives

This review collects together the crystallographic data of organotin compou nds by type and complexity, with a view to identifying correlations between properties and structure. Because of the large number of such structures, this first part deals only with monomeric derivatives, which covers almost one thousand structural determinations. While coordination numbers range fr om two to eight, for two and three coordination only tin(ll) compounds are found. All others are tin(IV) except for four examples with coordination nu mber four, and ten with coordination number five. The predominant geometrie s are tetrahedral, trigonal bipyramidal, pseudo-octahedral and pentagonal b ipyramidal. The most common C-donor ligands are methyl and phenyl. There ar e examples of distortion and structural isomerism.
