Coordination mode-tuned stacking motif in alkali metal salts of Ni(pdt)2 complexes (pdt = 2,3-pyrazinedithiol) and its physical properties

A series of alkali metal salts of bis(2,3-pyrazineditiolate) nickel complexes, Ni(pdt)2, were synthesized. The stacking motifs of Ni(pdt)2 and resultant physical properties were quite different depending on the alkali metal cations. The difference in physical properties was reasonably explained by the crystal structures.
