Two new ion-pair complexes [Co(BBP)₂]₂[Ni(mnt)₂]Cl₂·4DMF·2H₂O (1, BBP=2,6-bis(benzimidazol-2'-yl) pyridine, mnt=maleonitriledithiolate) and [(Py)₂CH₂][Co(mnt)₂]₂·4DMF (2) have been synthesized and characterized by elemental analyses, IR spectroscopy, thermogravimetric analyses and single-crystal X-ray diffraction. X-ray diffraction studies show that complex 1 crystallizes in monoclinic, space group P2₁/c. The crystal of 2 belongs to a triclinic system with space group P1. Due to the hydrogen bonding interactions, anions and cations formed the mixed packing in complex 1 while the anions and cations formed segregated columns in 2. In addition, thermogravimetric analyses of the two complexes are also investigated.
