Abstract

A series of alkali metal salts of bis(2,3-pyrazineditiolate) nickel complexes were synthesized. In these complexes, the Ni(pdt)₂ units were arranged in one-dimensional stacks. The stacking motifs and resultant physical properties were quite different depending on the alkali metal cations, which are coordinated by the N atoms of the pdt ligands. Lithium salts showed alternating stacks of monomeric and dimeric Ni(pdt)₂ moieties. Potassium and cesium salts showed one-dimensional stacks of monomeric and dimeric Ni(pdt)₂ moieties, respectively. Sodium salt showed phase transition between monomeric and dimeric structures at around 220 K. The difference in physical properties was reasonably explained by the crystal structures.
