Dibut-yl[N-(5-chloro-2-oxidobenzyl-idene)-l-isoleucinato-?O,N,O']tin(IV).

ABSTRACT: The Sn(IV) atom of the title compound, [Sn(C(4)H(9))(2)(C(13)H(14)ClNO(3))], adopts a distorted SnNC(2)O(2) trigonal-bipyramidal geometry with a mean Sn-C distance of 2.105?Å and with Sn-O = 2.107?Å, and forms five- and six-membered chelate rings with the tridentate ligand. One butyl group is disordered over two positions with site occupancies of 0.65?(1):0.35?(1).
