(CV+)[Ni(dmit)(2)](.)1/2(C6H6) (1) and (BF+)[Ni-(dmit)(2)] (2) (dmit = 2-thioxo-1,3-dithiole-4,5-dithiolato, CV+ = cation of Crystal Violet, BF+ = cation of Basic Fuchsin) were prepared and characterized by X-ray crystal structural analysis. In the crystal structure of 1, the Ni(dmit)(2) unit was bent at Ni in a V shape with an angle of 13.7 and tetrahedral distortion of 8.8 degrees around Ni was also present that originated from the steric effect of the propeller-shaped CV cation. In the case of 2, BF and [Ni(dmit)(2)](-) formed an independent stacking column in which [Ni(dmit)(2)](-) were stacked alternately rotated with an angle of 90 degrees to each other. I and 2 exhibited semiconducting behavior with room-temperature conductivities of 2.9 x 10(-7) and 9.0 X 10(-5) S cm(-1), respectively.
