abstract = "Cobalt(II) complexes of N-methyl phenyl, 1-phenylpiperazyl, and morpholinyl dithiocarbamates have been synthesized and characterized by UVVisible, FTIR, 1H-, 13C-NMR, and mass spectrometry. The spectroscopic data indicated that two ligands coordinated in
bidentate chelating to the metal ion to form four-coordinate cobalt(II) complexes (13), which was confirmed by mass analysis (TOF MS ES+) of the complexes with m/z [M]+ = 450.98, 382.94, and 382.94 for 1, 2, and 3, respectively.
Single crystal analysis of 2A and 3A show centrosymmetric mononuclear cobalt(III) bonded to three dithiocarbamate ligands forming a distorted octahedral geometry, indicating the cobalt(II) undergoes aerial oxidation to cobalt(III) during recrystallization. In addition, 2A
crystallized with one solvated molecule of toluene. The redox behaviors of the complexes were studied by cyclic and square wave voltammetry in dichloromethane; the result revealed a metal centered redox process consisting of a one-electron quasi-reversible process assigned to Co(III)/Co(IV)
oxidation and a corresponding Co(IV)/Co(III) reduction. RandlesSevcik plots (anodic peak current versus the square root of the scan rate (Ip,a versus 1/2)) for the redox couples revealed diffusion-controlled behavior.",
