The novel dioxomolybdenum(VI) complexes with methyl (1), ethyl (2), n-propyl (3), i-propyl (4), n-butyl (5) and cyclohexyl (6) ester of 2-mercaptonicotinic acid have been prepared in the reactions of MoO2Cl2 and MoO2-(acac)2 (acac = 2,4-pentandionate) with mercaptonicotinic acid in corresponding alcohol. The esterification reaction was catalyzed by MoV originated from the reduction of MoVI with mercaptonicotinic -SH group with simultaneous formation of S-S bond resulting from the condensation of two 2-mercaptonicotinic molecules. The presence of MoV was proved by ESR spectra. The molecular and crystal structures of 1, 2, 3 and 4 as well as of the by-products 1,1'-dithio-2,2'-n-butylnicotinoate (7) and tetramethylammonium hexachloromolybdate(V) (8) have been determined by a X-ray single crystal diffraction. The complexes 1-4 contain MoO22+ core with octahedral coordination of each molybdenum atom complexed by two 2-mercaptonicotinato N and S donor atoms. ΠWILEY-VCH Verlag GmbH, D-69451 Weinheim, 2001.
