Two new salts, [NO2BrBzPy]2[M(mnt)2] ([NO2BrBzPy]+= 1-(2'-bromo-4'-nitrobenzyl)pyridinium; mnt2-= maleonitriledithiolate; M = Ni(1), Pd(2)) have been prepared and characterized by elemental analyses, IR, UV, ESI-MS spectra, TG, and single-crystal X-ray diffraction. The results reveal that when the metal ion is changed from Ni(II) to Pd(II), the crystal system, and the dihedral angles between the phenyl and pyridine rings and the C-C-N reference plane of the cation, and the stacking modes of the anions and the cations are evidently different. Some weak interactions such as C-H center dot center dot center dot Br, C-H center dot center dot center dot O, C-H center dot center dot center dot N and C-H center dot center dot center dot S hydrogen bonds, p[image omitted] or [image omitted] stacking interactions in 1 and 2 play important roles in the molecular stacking and generate a 2D structure.
