A new hybrid organic-inorganic salt, [4CNBzDMAP]2 [Cu(mnt)2] (mnt2-= maleonitriledithiolate; [4CNBzDMAP]+= 1-(4'-cyanobenzyl)-4-dimethylaminopyridinium) was synthesized and characterized by elemental analyses, IR, UV, molar conductivity , single crystal X-ray diffraction and magnetic measurement. The crystal belongs to the triclinic system, space group P-1 with cell constants a = 7.0785(9) angstrom, b = 11.3432(14) angstrom, c = 13.1406(16) angstrom, = 71.784(1)degrees, = 81.772(1)degrees, = 82.663(1)degrees, Z = 1. The structure was solved by direct methods and refined to R1= 0.0343 (wR2= 0.1186). The [Cu(mnt)2]2 - anions and the [4CNBzDMAP]+ cations in 1 stack alternately and form a 1D column via center dot center dot center dot stacking interactions. Weak C-H N hydrogen bonds between [Cu(mnt)2]2 - anions and [4CNBzDMAP]+ cations of the adjacent columns further generate a 3D network structure. The magnetic susceptibility of 1 measured in the temperature range 2.0-310 K shows weak antiferromagnetic coupling feature with = -0.0775 K.
