Metal Thiocyanato Complexes: Synthesis, Magnetic, and Spectral Studies of Some Mixed‐Ligand Thiocyanato Complexes of Nickel(II) Involving Benzothiazole and Benzimidazole Derivatives
摘要:
A new series of mixed-ligand thiocyanato complexes of nickel(II) of the compositions [Ni(NCS)(2)(L)(4)], where L = 2-mercaptobenzothiazole (2-MBZT), 2-(2'-hydroxyphenyl)-benzothiazole (2'-HPBZT), 2-(2'-tolyl)benzothiazole (2'-TOBZT), 2-(3'-tolyl)benzothiazole (3'-TOBZT), [Ni(NCS)(2)(2-AMBZT)(2)] and [Ni(NCS)(2)(BBZLY)(H2O)(2)], where 2-AMBZT = 2-aminobenzothiazole and BBZLPY = 2,6-bis(benzimidazole-2'-yl)pyridine, has been synthesized by the interaction of nickel(II) thiocyanate with the respective ligands. The compounds so obtained were characterized by analytical data, molar conductances, magnetic measurements, infrared and electronic spectral studies. Suitable octahedral structures have been suggested for these complexes.
