摘要: A general method for the preparation of dioxotungsten(VI) complexes type [WO2L(MeOH)] (where LH2 = Schiff’s base derived from salicylaldehyde or o-vanillin and benzoylhydrazide, salicylhydrazide, furoylhydrazide, isonicotinoylhydrazide) using [WO2(acac)2] (acacH acetylacetone) as a precursor, is described. These have been characterized by elemental analysis, electrical conductance, IR, electronic, NMR spectral, electrochemical, magnetic susceptibility measurements. The structure [WO2(o-C6H4CH=NN=C(O)C6H5)(MeOH)]·MeOH (1a·MeOH) has determined single-crystal X-ray diffraction analysis. 1a·MeOH crystallizes in space group Pbc21 with 6.992(2), b 16.190(2), c 31.390(4) A, V 3553.4(12) A3, Z 8, RF 0.050, Rw 0.054. tungsten atom highly distorted octahedral coordination which anionic oxygen atoms tridentate ligand are mutually trans cis to cis-dioxo group.
