Triorganotin(IV) Benzoates and Aminobenzoates

Article abstract of DOI:10.1016/0022-328X(87)80322-4

Complexes of the general formula R3SnX, where X is the anion of benzoic acid, o-, m-, p-amino- or N-phenyl-o-amino-benzoic acid, have been prepared and characterised.A combination of molecular weight, infrared, 1H NMR and 119Sn Moessbauer measurements show that, the amino-nitrogen atoms are not coordinated to tin.When R= phenyl or cyclohexyl, the compounds are monomeric and four-coordinate, and when R is alkyl (Me, n-Pr, n-Bu) they are monomeric and five-coordinate, with a bidentate carboxylate in the equatorial position of a trigonal bipyramidal structure.
