Abstract
Reactions of ammonium molybdate tetrahydrate, ammonium thiocyanate, and hydroxylammonium chloride as a reducing agent in aqueous solution probably afforded a specie containing the Mo-N≡O fragment, which was further treated with ammonium polysulfide to result in isolation of two tetranuclear molybdenum(IV) sulfur nitrosyl complexes (NH4)4Mo4(μ4-S)(μ3-S)2(μ-S2)4(η2-S2)(NO)4·4H2O (1) and (NH4)4Mo4(μ4-O)(μ-S2)6 (NO)4 (2). Two tetranuclear molybdenum(IV) complexes were characterized spectroscopically by ultraviolet spectrophotometer UV-3000 and infrared spectrophotometer FTS-40, and their structures were determined by single-crystal X ray diffraction, the results show that the two complexes containe nitrosyl group, their electrochemical properties were also investigated.
