英文摘要	A new molecular conductor ( PyH) [ Ni ( dmit)(2)](2) ( Py = pyridine, dmit = ( C3S5)(2-) = 4,5-dimercapto-1,3-dithiole-2-thione) has been prepared by oxidation with I-2/NaI and characterized by elemental analysis and IR spectrum. The single crystal structure was determined by four-circle X-ray diffraction method. Crystallographic parameters for (PyH) [Ni(dmit)(2)](2): triclinic system; P-1 space group; a = 0.59227 (4) nm, b =0.82279(6) mn, c = 1.67535(9) nm, alpha = 90.233(5)degrees, beta = 92.107(6)degrees, gamma = 104.654(6)degrees; V = 0. 78925 (9) nm; Z = 1. Both [Ni (dmit)(2)](-0.5) anion and PyH+ cation are almost planar. [Ni(dmit)(2)](-0.5) is stacked to form columns of dimerised pairs along the b-axis. Short and intense (SS)-S-... contacts in side-by-side style build a kind of two-dimensional network in the (001) plane. The conductivity at one direction on (001) plane at room temperature was measured to be 0.13 Omega(-1) (.) cm(-1). Along the c direction the sheets of conductive [Ni(dTnit)(2)](-0.5) are structurally modulated by hydrogen bonds between anions and cations. The resistivity-temperature curve in the temperature range of 90 - 290 K shows that the title compound behaves as a semiconductor with quite narrow energy gap.
