摘要：

Copper(II), iron(III), cobalt(II,III), nickel(II), chromium(III), palladium(II), platinum(IV) and zinc(II) complexes of 2methyl7hydroxy5methoxy6formyl chromone thiosemicarbazone (H2L1), 2methyl5,7dimethoxy6formyl chromone thiosemicarbazone (HL2) have been prepared and characterized by conductance, magnetic, electronic, infrared and 1H NMR spectroscopic measurements as well as elemental and thermogravimetrical analyses. Octahedral structures are proposed for the Pt(IV), Fe(III), Co(II), Co(III), and Cr(III) complexes, whereas squareplanar configurations are suggested for the Pd(II)and Cu(II) complexes. Moreover, spectral studies indicate that the H2L1Ni complex is squareplanar and the H2L1Zn(II) complex is tetrahedral.
