[Mn(S₂C₆H₃Me)2]ⁿ⁻: Mononuclear Manganese Complexes with Square‐Planar (n = 1) and Distorted Tetrahedral (n = 2) Sulfur Coordination

Abstract

The unusual planar manganese(III)-sulfur complex [Mn(S2C6H3Me)2]−1 is formed on reaction of MnCl2·4H2O with toluene-3,4-dithiolate in methanol in the presence of atmospheric oxygen. A further product is the square-pyramidal complex containing an additional apical MeOH group. Reaction under anaerobic conditions leads to formation of the manganese(II)-sulfur complex [Mn(S2C6H3Me)2]2−, which differs from 1 through its strongly distorted tetrahedral coordination.
