Synthesis, Spectral and Magnetic Investigation of 4(2-Pyridyl)-Isatin-3-Thiosemlcarbazone Complexes

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.
