Abstract

In acetonitrile, the cis-[MoO2]2+ group present in the anionic complex [MoO2(o-SC6H4COO)2]2-, can be functionalized under mild conditions by reaction with arylhydrazines, p-R-C6H4NHNH2. The resulting ionic complexes have been formulated as [Et3NH]2[Mo(NNC6H4-p-R) 2(o-SC6H4COO)2], R=H, [Et3NH]2[I]; Me, [Et3NH]2[II]; MeO, [Et3NH]2[III]; Cl, [Et3NH]2[IV]; NO2, [Et3NH]2[V], characterized by spectroscopic methods and, additionally, in the case of complex [Et3NH]2[IV], by single crystal X-ray diffraction. The aryldiazenido ligands, occupying mutually cis positions, adopt the "singly bent" geometry.
