The newcomplex, [IBzPyCH 3 ][Ni(bdt) 2 ] (1), has been synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction, in which [IBzPyCH 3 ]+ = 1-(4-iodobenzyl)-3-methylpyridinium and bdt 2 − = 1,2-benzene- dithiolate. The X-ray structure analysis shows that the anions are centrosymmetric, the two nonequivalent anions form different uniform-spaced stacking
