Synthesis and characterization of transition metal dithiocarbamate derivatives of 1-aminoadamantane: Crystal structure of (N-adamantyldithiocarbamato)nickel(II)

Four bis(N-adamantyldithiocarbamato)metal(II) complexes [M(S2CNHC10H15)2] (M = Ni, Zn, Cd, and Hg) were prepared by metathesis of the corresponding potassium salt, K[S2CNHC10H15]. Characterization of the prepared complexes shown that the presence of only one band in the region 1000 cm−1 in IR spectra can be attributed to a completely symmetrical bonding of the dithiocarbamate ligand, acting in a symmetrical bidentate mode. Also the short thioureide C–N distance in X-ray analysis of Ni complex confirm the delocalization of the π electrons over the S2CN moiety and strong double bond character.

Graphical abstractFour bis(N-adamantyldithiocarbamato)metal(II) complexes of Ni, Zn, Cd, and Hg were prepared by metathesis of the corresponding potassium salt with transition metal salts. The structure of complexes was characterized by IR, 1H and 13C NMR, UV and CHN analysis. Also, the Ni complex was crystallographically characterized. Furthermore, the physical behavior of the Ni complex was evaluated by thermal gravimetric analysis.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► bis(N-adamantyldithiocarbamato)metal(II) complexes. ► Complexes were characterized by IR, 1H and 13C NMR, UV and CHN. ► Ni complex was crystallographically characterized.
