Synthesis,crystal structure and magnetic property of a novel ion-pair nickel (III) complex containing 1,2-benzenedithiolate

摘要

A new ion-pair complex [1-(4-nitrobenzyl)pyridinium][Ni(bdt)2] (1),in which bdt~(2-)=1,2-benzenedithiolate,has been synthesized and characterized.The X-ray structure analysis shows that the anions are centrosymmetric,the two non-equivalent anions form different uniform-spaced stacking pattern and the weak H-bonding interactions of C-H…S were observed in 1.The temperature dependence of magnetic susceptibilities of 1 indicates ferromagnetic behavior in the antif erromagnetic exchange system,which may arise from spin-canting.
