The flexibly-bridged hexadentate tetraanionic ligands, LH4 , react with in a 1:2 molar ratio in refluxing methanol to give complexes of the type .These complexes show an intense ν(Mo=O) band at 924-948 cm-1 and a broad but strong band at ca. 850 cm-1 due to weakened ν(Mo=O) as a result of MoO->Mo interactions.An oligomeric structure, in which each Mo(VI) ion achieves a pseudo-octahedral structure via MoO->Mo bridging, has been suggested for these complexes. reacts with monodentate ligands (D) like pyridine, 4-methylpyridine, and dimethylsulfoxide and forms six-coordinated complexes of the type which are monomers.Cyclic voltammetry measurements indicate that these MoVIO2 complexes are resistant to MoIVO reduction.
