A New Method of Synthesis of Monomeric Aryloxide Complexes of Manganese(II): Structures of Manganese Phenoxides

Monomeric manganese(II) complexes of bulky alkyl/ aryl‐substituted phenoxides, [Mn{C 6 H n R m O} 2 (DME)] [ 1 : R = C 6 H 5 , n = 3, m = 2 (2,6); 2 : R = Me 3 C, n = 3, m = 2 (2,6); 3 : R = Me 3 C, n = 2, m = 3 (2,4,6)] were prepared in yields of 37, 44 and 72 %, respectively, from the reaction of manganese powder, Hg(C 6 F 5 ) 2 and the corresponding phenol in the presence of a little mercury in dimethoxyethane (DME). The compounds were characterized spectroscopically and by magnetic measurements. The single crystal structures of 1 and 3 and also of the mixed phenoxide complex [Mn{(C 6 H 3 (C 6 H 5 ) 2 ‐2,6‐O}{C 6 H 3 (Me 3 C) 2 ‐2,6‐O}(DME)] 4 are reported.
