An ionic pair complex, [FClBzDMAP](2)[Pd(mnt)(2)] (1), ([FClBzDMAP]( )= [1-(4'-fluoro-2'-chlorobenzyl)-4-dimetylamino pyridinium, mnt(2)- = maleonitriledithiolate), was synthesized and characterized by elemental analyses, IR, UV-vis spectra, molar conductivities and single crystal diffraction. The crystal belongs to the triclinic system, space group P-1 with cell constants a = 8.3472(8)angstrom, b= 9.3988(9) angstrom, c= 13.5875(14) angstrom, alpha = 76.676(1)degrees, beta = 86.036(1)degrees, gamma = 71.182(1)degrees, Z = 1. It is interesting that the [FClBzDMAP]( ) cations (C) and the [Pd(mnt)(2)](2-) anions (A) in 1 stack into a 1D alternating CC-A-CC-A-CC column along ab direction, while the cations form a 1D column along bc direction. Some weak interactions such as p center dot center dot center dot pi, pi center dot center dot center dot pi, Cl center dot center dot center dot S, and C-H center dot center dot center dot N interactions in the crystal play important roles in the self-assembly process and give rise to a 3D network structure.
