The disodium salt of the tris(catecholato) complex of manganese(IV), [Na2MnIV(DTBC)3·6MeCN], has been synthesized and isolated as dark blue irregular crystals. The structure of the complex, as determined by single-crystal X-ray diffraction methods (hexagonal, R3; a = 14.548 (6) A?, c = 49.731 (9) A?; Z = 6), is a nearly symmetric octahedral array of oxygen donor atoms (from the three catechol ligands) about the manganese(IV) ion. The proton and 13C NMR spectra for the complex in Me2SO-d6 and pyridine-d5 indicate that it maintains its main structural features in solution. The reactions of the blue MnIV(DTBC)32- complex and its green reduction product, MnIII(DTBC)2(H2O)2-, with superoxide ion in aprotic media have been characterized by spectroscopic, magnetic, and electrochemical studies.
