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.

以三(1,10-菲罗啉)镍(II)为反阳离子的半导体镍(II)二硫代酸盐的合成、x射线结构表征和电化学研究

离子对配合物[Ni(o-phen)3][Ni(L)2]2。合成了CH2Cl2 (1) [L = 1,2-二苯基乙烯-1,2-二硫代酸酯，o-phen = 1,10-菲罗啉]并对其进行了x射线晶体学表征。由循环伏安法得到的溶液结构1与固态分子结构非常吻合。电化学分析得到的氧化还原峰在一定程度上是[Ni(o-phen)3]2+和[Ni(L)2]各自得到的氧化还原峰的组合。此外，本文还分析了o-phen在[Ni(L)2]上加成合成标题配合物的反应方案。1以固态形式导电。电导率在308 K(35°C)到423 K(150°C)的温度范围内变化。发现该化合物在150°C后热不稳定。图示:离子对配合物[Ni(o-phen)3][Ni(L)2]2。合成了CH2Cl2 (1) [L = 1,2-二苯乙烯-1,2-二硫酯]，并用x射线晶体学对其进行了表征。在溶液中的电化学表征中，1的循环伏安法得到的氧化还原峰(还原)是[Ni(o-phen)3]2+和[Ni(L)2]单独得到的峰的组合。它还能像半导体材料一样以固态导电。

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.
