Synthesis and Characterization of Pyrrole-2-Thiocarbgxamide Complexes with Some Bivalent Metal Ions

Abstract

Pyrrole-2-thiocarboxamide, HNC₄H₃C(S)NH₂ (ptca), complexes having 1:2 metal-ligand stoichiometry have been prepared and cnaracterized by elemental analyses, molar conductance, magnetic susceptibility, electronic, esr, ir and nmr (¹H and ¹³C) spectral studies. Tetrahedral stereochemistry around Co(II), Ni(II), Zn(II), Cd(II) anHg(II) and five coordinate geometry around Cu(II) have been proposed on the basis of magnetic and spectral studies.
