Summary
New dioxomolybdenum(VI) complexes [MoO2LD] (LH2=Schiff base derived from isonicotinylhydrazide and salicylaldehyde, 2-hydroxynaphthaldehyde and 2-hydroxyacetophenone and benzoylhydrazide and 2-hydroxyacetophenone; D=H2O, HCONMe2, C5H5NO, C4H8O or Me2SO) have been synthesized and characterized. The complexes contain acis-MoO2 moiety. The difference betweenv sym andv asymm of MoO2 is related to the basicity and ligand repulsion of the ligand (L) and the donor power of D. All the complexes decompose before melting and their thermal stability is in the order: C4H8O < HCONMe2 < Me2SO < C5H5NO < H2O. The complexes are monomeric, non-electrolytes in solution in MeOH, MeCN and PhNO2 and are diamagnetic.
