Abstract
A series of mononuclear anthracene-based dithiocarbamate Ni(II) complexes were readily prepared from one-pot reaction between corresponding secondary amine and nickel salt in the presence of carbon disulfide. X-ray crystallographic data reveals the marked difference in square planar structures of Ni(II) dithiocarbamate complexes with and without the presence of chloro and thiocyanato auxiliary ligands. Also, various intermolecular interactions of the complexes in the solid state such as π–π stackings, Ni···S linkages and CH···Ni anagostic bonds are detected. The 1H-NMR results evidently show the steric effect of the anthracenyl and dithiocarbamate moieties upon complexation. Importantly, phosphorus and proton magnetic resonance spectroscopies are tools to probe the facile transformation of the mixed-ligand complexes 3 into the congeners 1 in the solution. The absorption and emission spectral data describe the influence of anthracenyl rings on the photophysics of the complexes 1 and 2.
