(2-{[1,1-Bis(hy-droxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-4-chloro-phenolato-κO,N,O')dibutyl-tin(IV).

In the title compound, [Sn(C(4)H(9))(2)(C(11)H(12)BrNO(4))], the Schiff base ligand chelates to the Sn(IV) atom through the two deprotonated hy-droxy groups, as well as through the N atom, to confer an overall cis-C(2)SnNO(2) trigonal-bipyramidal geometry at the Sn(IV) atom [C-Sn-C = 129.92 (9)°]. The remaining methyl-enehy-droxy groups engage in O-H⋯O hydrogen bonding with the O atoms of adjacent mol-ecules, leading to infinite supra-molecular chains propagating in [001].
