Synthesis and Characterization of Transition Metal Complexes of Potassium 3‐(Pyridine‐4‐Carbonylmethyl)‐Dithiocarbazate

Abstract

AbstractThe preparation and characterization of some dipositive metalion complexes de rived from potassium 3‐(pyridine‐4‐carbonylmethyl)‐dithiocarbazate (PCDHK) are reported. The solid complexes of the composition ML·nH2O (M=Cu(II), Co(II), Mn(II), Zn(II), Cd(II), Ni(II), Pb(II), L = PCD−2, n = 0, 1, PCD−2=PCDHK‐K+‐H+) and ML2·2H2O (M=UO2(IV), L=PCDH−1, PCDH−1=PCDHK‐K+) have been characterized by elemental analyses, IR, UV, and 1HNMR spectra. The IR spectral data indicate that PCDHK be haves as either a mononegative or binegative ligand and coordinates in a tridentate or bridging tetradentate manner.
