Abstract
The SnIV atom in the title compound, [Sn(CH3)2(C18H11BrN2O3)], shows a distorted cis-C2NO2Sn trigonal-bipyramidal coordination geometry, with an axial O—Sn—O angle of 155.27 (9)°. The presence of an intramolecular O—H⋯N hydrogen bond between the amido N atom and hydroxy H atom in the Schiff base ligand helps to stabilize the overall molecular structure.
