Abstract

The configuration about the Sn centre in the title compound,[Sn (CH3) 3 (C10H13N2O2)], is intermediate between tetrahedral and trigonal bipyramidal. A weak intramolecular Sn⋯ O (carbonyl) interaction of 3.070 (3) Å gives rise to an intramolecular six-membered chelate ring, formed through the carbonyl O atom; this a unique feature of tetraorganotin compounds. The title compound was prepared by consecutive reaction of 3-(tert- ...
