Abstract

The crystal structure of chlorido{μ-2-[(2-oxidobenzylidene)amino]ethanolato-κ(4)O,N,O':O'}{2-[(2-oxidobenzylidene)amino]ethanolato-κ(3)O,N,O'}trivinylditin(IV), [Sn2(C2H3)3(C9H9NO2)2Cl], is disordered above 178 K. A doubling of the unit-cell volume is observed on cooling. The asymmetric unit at 93 K contains two ordered molecules. The phase transition corresponds to an order-disorder transition of one vinyl group bound to the Sn(IV) atom.

Keywords: crystal structure; dinuclear tin(IV) complex; enantiotropic phase transition; order–disorder.
