Two new salts, [1-NaMe-2-NH2Py](2)[Ni(mnt)(2)] (1) and [1-NaMe-2-NH2Py](2)[Ni(i-mnt)(2)] (2) ([1-NaMe-2-NH2Py](+) = 1-(1'-naphthylmethyl)-2-aminopyridinium, mnt(2-) = maleonitriledithiolate, and i-mnt(2-) = iso-maleonitriledithiolate), have been obtained and characterized by elemental analyses, infrared (IR), ultraviolet (UV), mass spectroscopy (MS), molar conductivities, and singlecrystal x-ray diffraction. The results have shown that the change of the ligand from mnt to i-mnt results in differences in the crystal system, space group, weak interactions, and the stacking mode of the cations and anions. The effects of weak interactions such as C-H center dot center dot center dot N, N-H center dot center dot center dot N, or C-H center dot center dot center dot Ni hydrogen bonds and p center dot center dot center dot pi, pi center dot center dot center dot pi, and C-H center dot center dot center dot pi stacking interactions generate a three-dimensional (3D) network structure.
