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{C6HnRmO}2(DME)] [1: R = C6H5, n = 3, m = 2 (2,6); 2: R = Me3C, n = 3, m = 2 (2,6); 3: R = Me3C, n = 2, m = 3 (2,4,6)] were prepared in yields of 37, 44 and 72 %, respectively, from the reaction of manganese powder, Hg(C6F5)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{(C6H3(C6H5)2-2,6-O}{C6H3(Me3C)2-2,6-O}(DME)] 4 are reported.
