Effect of metal (M) and counter ion nature on crystal structure and conducting properties of M(dddt)2 cation complexes

The effect of metal (M=Ni, Pt, Pd) and counter ion on crystal structure and conducting properties of M(dddt)2 bis(dithiolene) cation complexes is analyzed. The similarity and distinction in structures and properties of M(dddt)2 and ET salts are discussed.
