The metal complexes studied in this report derive from the ligand 4‐ N ‐phenylthiosemicarbazone‐2‐pyridinecarboxaldehyde, abbreviated HL, and the transition and post‐transition metals manganese, iron, cobalt, nickel, copper, silver, zinc, cadmium and lead. The new complexes were obtained by an electrochemical procedure and were found to be of the form ML 2 ·nH 2 O (n = 1−4) for divalent metals and ML·nH 2 O (n = 0, 4) for Cu and Ag metals. These complexes have been wholly characterized by elemental analysis, mass spectrometry, infrared spectroscopy, magnetic measurements and molar conductivities. NMR studies in solution ( 1 H, 113 Cd and 207 Pb NMR) were also performed. [MnL 2 ]·CHCl 3 ( 1 ), [ZnL 2 ]·CH 3 CN ( 2 ) and [CdL 2 ]·CH 3 CN ( 3 ) could be crystallographically characterized and their crystal structures show the metal atoms in a distorted octahedral environment.
