Abstract: The O-C₆H₄-CH=N-C₆H₄-O dianion of the title compound, [Mn(C₁₃H₉NO₂)(C₇H₅O₂)(C₂H₆OS)], acts as an O,N,O'-chelate to bind to the Mn^III atom, and the three atoms constitute three points [O-Mn-O = 174.43 (11)°] of an octahedron around the metal atom. The azomethine linkage is disordered over two positions in a 0.657 (13):0.343 (13) ratio. The deprotonated salicyldehyde anion acts as an O,O'-chelate; the sixth coordination site is represented by the O atom of the dimethyl sulfoxide molecule. The crystal studied was a non-merohedral twin with a minor twin component of 14.2 (3)%.
