Four bimetal ion-pair complexes,[NiL][M(dmit)_2](L=hmtade,M=Ni(1);L=hmta,M=Ni(2) ; L =hmtade,M = Hg(3);L=hmta,M=Hg(4),where hmtade =5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene,hmta=5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane,dmit =4,5-dimercapto-1,3-dithiole-2-thione) were synthesized and characterized by elemental analysis,IR,~1H NMR,UV-vis,thermogravimetry and cyclic voltammetry.The results showed that N-H…S hydrogen bonds were formed between hmtade/hmta and dmit ligands in the ion-pair complexes.All of the nickel ions of complex cations are five coordination.The S atom of[M(dmit)_2]~(2-)complex anion coordinates to Ni(Ⅱ) ions of tetraazamaerocycle complex cation.The stability sequence of the ion-pair complexes is:2>1>3>4.
