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].
在标题化合物[Sn(C₄H₉)₂(C₁₁H₁₂BrNO₄)]中,席夫碱配体通过两个去质子化的羟基以及氮原子与Sn(IV)原子螯合,在Sn(IV)原子处形成一个整体的顺式-C₂SnNO₂三角双锥几何构型[C-Sn-C = 129.92 (9)°]。其余的亚甲基羟基与相邻分子的氧原子形成O-H⋯O氢键,导致在[001]方向上延伸的无限超分子链。
