The synthesis of known MoO2MeS2 from MoO2Cl2 and MgMeS2 (1 : 1) in THF is accompanied by the formation of monomesityl molybdenum compounds. From ligand exchange and reduction arise [MesMoCl3]- (3a) and [Mes-MoO3]- (3c). 3a and 3b crystallize in form of [(Mes-MoO3)2{Mg2Cl2(THF) 5}2][MesMoOCl3]2(THF)2, which has been characterized by X-ray structural analysis. In 3 two MesMoO3 units are linked in a ring-like manner via magnesium ions. The anion 3a, which possesses a distorted trigonal-bipyramidal arrangement, was also isolated as [Mg(THF)6][MeSMoOCl3]2 which was investigated by X-ray analysis. The reaction of MoO2Cl2 with MgMeS2 in a 1 : 0,5 ratio generates the compounds [Mg(THF)4(MoO3Cl)2] and MoOCl3(THF)2. Reaction pathways which may lead to these compounds are discussed.
