The synthesis and characterization of cis-[MoO2(L) (solv)] [L = salicyliden
e salicyloyl hydrazine and solvent=H2O/MeOH) is described. The tridentate S
chiff base ligand was obtained by the condensation of salicylaldehyde and s
alicylic acid hydrazide in 1:1 ratio. The dioxomolybdenum complex was isola
ted from 1:1 reaction mixture containing the Schiff base ligand and MoO2(ac
ac)(2). The orange colored, non-electrolytic and diamagnetic compound was c
haracterized by elemental analyses, spectroscopic techniques (IR,H-1 NMR an
d UV-Vis), and cyclic voltammetry. The molecular structure was determined u
sing crystals obtained from methanol, confirmed the formula cis-MoO2(L)(CH3
OH) with triclinic P-1 space group. The Mo is coordinated by two cis termin
al Os, ONO from the ligand and O of methanol. The oxo-transfer reaction fro
m cis-[MoO2(L)(solv)] to PPh3, is reported. (C) 1999 Elsevier Science Ltd.
