CRYSTAL STRUCTURE AND ELECTRICAL CONDUCTIVITY OF (Et4N)0.5[Ni(dmit)2]

The crystal of (Et4N)0.5[Ni(dmit)2] belongs to triclinic system (dmit: isotrithionedithiolate). In the crystal, face-to-face stacking and side-by-side arrangement of Ni(dmit)2 molecules form the two-dimensional S···S networks, which are weakly connected in the third direction by thioketone sulfur atoms in the isotrithione ring. The electrical conductivity measurements show that (Et4N)0.5[Ni(dmit)2] is a semiconductor with small anisotropy.
