Two new salts based on [Ni(tdas)2]2 - (tdas2 - = 1, 2, 5-thiadiazole-3,4-dithiolate) anion with substituted benzylpyridinium cation, [BzPy][Ni(tdas)2] (1) and [NO2BzPy]2[Ni(tdas)2] (2), have been prepared by reaction of Na2tdas, NiCl2.6H2O, and 1-Rbenzylpyrid-inium bromide [RBzPyBr, R = H(1), NO2(2)]. Single-crystal X-ray diffraction analyses indicate that the two salts crystallize in a monoclinic system with space group C2/c, but the stacking modes of the anions and the cations are different. Some intra-molecular contacts such as p center dot center dot center dot , center dot center dot center dot , or C-H center dot center dot center dot N weak interactions in 1 and 2 play important roles in the molecular stacking and generate a 2D structure. In addition, IR, UV, MS, molar conductivities and effect on crystal structures 1 and 2 are successively described.
