Synthesis, spectral elucidation, electrochemistry and DFT interpretation of manganese(II)-thioalkyl-arylazoimidazole complex
چکیده انگلیسی
One new Mn(II) thioalkyl-arylazoimidazole complex (1), [Mn(SRaaiNR/)2(SCN)2] (SRaaiNR/ = 1-alkyl-2-{(o-thioalkyl)phenylazo}imidazole and R = Me, R/ = Et) is afforded and systematically characterized by FT-IR, UV-Vis and EPR spectroscopy. The single crystal X-ray diffraction technique reveals that in complex 1, the central Mn atom possesses a tetrahedral environment of MnN4 sphere; coordinated by a pair of monodentate orientation of Nimidazolyl and NSCN atoms. Variable temperature magnetic moment confirms that in complex 1, there exists an antiferromagnetic coupling in tetrahedral symmetry. Cyclic voltammogram study of complex 1 evidenced the presence of a Mn(III)/Mn(II) redox response at 1.25 V alongwith azo reductions at −0.8 V. DFT computational using optimized geometry clearly explains the electronic and redox properties which is in accordance with the experimental evidence.
