Abstract

One nickel(II)-dithiolene complex bis(1,2-diphenylethylene-1,2-dithiolate)nickel(II) has been synthesized and crystallographically characterized. The complex is square planar at its metal centre. The compound in its solid-state is found to conduct electricity at room temperature. Variation of conduction is also found on raising the temperature. Instead of a metal…metal orbital overlap, the electron density is expected here to pass through some other covalent and electrostatic bonds of the compound in solid-state resulting in electricity conduction.

A square planar nickel(II)dithiolene complex has been synthesized and characterized. Its conductivity was measured at varying temperatures. This revealed its semiconductivity in nature. The electrical conductivity of this complex has been explained by considering the long intermolecular distance and π…π stacking interaction. Molecular orbital calculations were also done to explain its electrical conductivity.

摘要

合成了一种镍（II）-二硫代镍配合物双（1,2-二苯基乙烯-1,2-二硫代）镍（II），并进行了晶体学表征。该复合体在其金属中心呈方形平面。发现固态化合物在室温下可以导电。升高温度也会发现导电变化。代替金属…金属轨道的重叠，这里的电子密度有望通过化合物的其他固态共价键和静电键，从而产生导电性。
