Abstract
An ion-pair complex [Ni(o-phen)3][Ni(L)2]2.CH2Cl2 (1) [L = 1,2-diphenylethylene-1,2-dithiolate, o-phen = 1,10-phenanthroline] has been synthesized and X-ray crystallographically characterized. The solution structure of 1, as derived from cyclic voltammetry, conforms well to the solid-state molecular structure. The redox peaks obtained from the electrochemical analysis of 1 are to some extent a combination of the peaks obtained individually for [Ni(o-phen)3]2+ and [Ni(L)2]. Moreover, the reaction protocol for the synthesis of the title complex by the addition of o-phen to [Ni(L)2] is analyzed electrochemically. 1 conducts electricity in solid-state. The electrical conductivity varied on varying temperatures from 308 K (35 °C) to 423 K (150 °C). The compound is found to be thermally unstable after 150 °C.
Graphical abstract
An ion-pair complex [Ni(o-phen)3][Ni(L)2]2.CH2Cl2 (1) [L = 1,2-diphenylethylene-1,2-dithiolate] has been synthesized and characterized by X-ray crystallography. On electrochemical characterization in solution, the redox peaks (reduction) obtained from the cyclic voltammetry of 1 are found to be a combination of the peaks obtained individually for [Ni(o-phen)3]2+ and [Ni(L)2]. 1 also conducts electricity in a solid state like a semiconducting material.
