The role of bivalent tin compounds in platinum co-ordination chemistry; X-ray structure of [Pt{Sn(NR′2)2}3], trans-[(Pt(µ-Cl)(PEt3){SnCl(NR′2)2})2], and (SnClR2)2[R = CH(SiMe3)2, R′= SiMe3]
Abstract
Bivalent tin compounds SnX2 behave in one of three ways towards platinum substrates: (a) as neutral ligands, (b) as co-ordinatively unsaturated fragments by inserting into Pt–Cl bonds, and (c) as reducing agents; these features are illustrated, inter alia, by X-ray data on the three title compounds.
