Butyl-trichlorido{2-[(diisopropyl-ammonio)-meth-yl]phen-yl}tin(IV) dichloro-methane monosolvate.

The title compound, [Sn(C(4)H(9))(C(13)H(21)N)Cl(3)]·CH(2)Cl(2), was obtained by recrystallization of [2-(diisopropyl-amino-meth-yl)phen-yl]tin(IV) butyl dichloride from a CH(2)Cl(2)/n-hexane mixture (1:4 v/v) in the presence of ambient moisture. Partial hydrolysis led to the title compound, the hydro-chloric acid adduct of the dichloride, having a penta-coordinated Sn atom with a trigonal-bipyramidal C(2)SnCl(3) core. The N atom of the 2-[(diisopropyl-ammonio)-meth-yl]phenyl ligand forms a strong intra-molecular N-H⋯Cl hydrogen bond, resulting in a zwitterionic species, [2-((i)Pr(2)HN(+)CH(2))C(6)H(4)]SnBuCl(3) (-)·CH(2)Cl(2). Disorder was found in the n-butyl group, which was refined as disordered over three positions, with site occupancies of 0.22 (1), 0.51 (1) and 0.27 (2).
