Abstract

Two bis(dithiolene)nickel(II) complexes of the type [Ni(L)₂] [L = 1,2-di(4-chlorophenyl)ethene-1,2-dithiolate (1) and 1,2-di(4-bromophenyl)ethene-1,2-dithiolate (2)] have been synthesized and characterized by different chemical and physicochemical methods. 1 was characterized by different spectroscopic and spectrometric techniques. The molecular structure of 2 was derived from the single crystal X-ray diffraction. The electrochemical activities of both complexes were investigated by cyclic voltammetry. Both the complexes were found to exhibit intense near-infra-red (NIR) absorptions.

Graphical Abstract

Two isostructural bis(dithiolene)nickel(II) complexes of general formula [Ni(L)₂] [L = 1,2-di(4-chlorophenyl)ethene-1,2-dithiolate (1) and 1,2-di(4-bromophenyl)ethene-1,2-dithiolate (2)] have been synthesized and characterized by different chemical and physicochemical methods. 2 was crystallized, and its molecular structure was derived from the single crystal X-ray diffraction. In spite of several efforts, crystallization of 1 was not possible. 1 was characterized by several spectroscopic and spectrometric methods. Redox activities of ligands of both complexes were investigated by cyclic voltammetry. Both the complexes were found to exhibit intense near-infra-red (NIR) absorptions.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
