Abstract
Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and UO2 2+complexes of isatin 4(2-pyridyl)-3-hiosemicarbazone, H2IPT, have been synthesed and characterized by elemental analyses, molar conductance, spectral (i.r., visible and n. m. r.) and magnetic moment measurements. I. r. spectra show that H2IPT behaves as a bidentate (ON or SN) end a tridentate ONS in a neutral or anionic form. An octahedral structure is proposed Co(HIPT)Cl.3H2O, Co(HIPT)2. 2H2 O, Si(HIPT)Ac.2H2 0 and Cu(H2IPT)2 (Ac)2 complexes and square-planar structure for the Cu(HIPT)Cl.2H2O complex on the basis of spectra and magnetic studies. The molar conductivities for all complexes were in the range of non-electrolytes.Keywords
