Abstract
Copper(II), nickel(II), palladium(II), platinum(II), and silver(I) complexes of 2‐acetylpyrrole thiosemicarbazone (H2L1) and copper(II), nickel(II), platinum(II) and zinc(II) complexes of 2‐acetylfuran thiosemicarbazone (HL2) have been prepared and characterized by conductance, electronic, infrared, magnetic and 1H NMR spectral measurements in addition to elemental and thermogravimetrical analyses. Square‐planar structures are suggested for the H2L1 complexes of Cu(II), Ni(II), Pd(II) and Pt(II), whereas octahedral structures proposed for the HL2 complexes of Cu(II) and Ni(II); the Zn(II) and Ag(I) complexes are tetrahedral. Moreover, the results showed that the ligand H2L1 is bidentate in all of its complexes, and the ligand HL2 is either mono‐, di‐ or tridentate.
