Four novel dimeric bis-μ-imido bridged metal–metal bonded oxidomolybdenum(V) complexes [MoV2O2L′21–4] (1–4) (where L′1–4 are rearranged ligands formed in situ from H2L1–4) and a new mononuclear dioxidomolybdenum(VI) complex [MoVIO2L5] (5) synthesized from salen type N2O2 ligands are reported. This rare series of imido- bridged complexes (1–4) have been furnished from...

The solution behavior of structurally characterized [VVO(OEt)(L)] complexes, which transform into the corresponding divanadium(V,V) compounds [{VVO(L)}₂-μ-O], is reported. Upon controlled potential electrolysis, the corresponding [(L)V₂O₃(L)]⁻ mixed-valence species are obtained upon partial reduction of the [(VVOL)₂-μ-O] formed in solution. All...
