Abstract

Abstract : Two new salts based on [Ni(tdas)2 ] 2− (tdas 2− = 1, 2, 5-thiadiazole-3, 4-dithiolate), [4FBz-4EtPy]2 [Ni(tdas)2 ](1 ) and [4BrBz-4EtPy]2 [Ni(tdas)2 ] (2 ), have been prepared by reaction of Na2 tdas, NiCl2 . 6H2 O, and [4RBz-4EtPy]Br([4RBz-4EtPy] + = 4-R-benzyl-4′-ethylpyridinium, R = F(1 ), Br(2 )), and characterized by elemental analysis, IR, UV-Vis, EI-MS spectra, and single-crystal X-ray diffraction. Two salts crystallize in different systems with the different stacking modes of the anions and the cations. The [4FBz-4EtPy] + cations in1 form a 1D chain through C−H···F hydrogen bonds, while the [Ni(tdas)2 ] 2− anions form a 1D chain in 2 through intermolecular short S···S interactions. Some other intra-molecular contacts such as C−H···S, C−H···N, C–H···Ni, π···π, S···N, and S···Br weak interactions in1 and2 play an important role in the stacking of the molecules and give further rise to a network 3D structure.
