Six new compounds: [M(dps)(dca)2]∞ (1, M = Cd; 2, M = Fe), [Cu(dps)(dca)2(CH3OH)2] ∞ (3), [M(dps)2(SCN)2(H 2O)2]∞ (4, M = Cd; 5, M = Fe), [Cu(dps)4(SCN)2]∞ (6), (dps = 4,4′-dipyridyl sulfide, dca = dicyanamide) were synthesized, characterized by FT-IR, element analysis and TG. Their structures were determined by single crystal X-ray diffraction. According to the structure analysis, compounds 1 and 2 are three-dimensional microporous frameworks constructed by Cu-dps-Cu and Cu-dca-Cu bridges; compound 3 shows a zigzag chain constructed by a Cu-dps-Cu bridge; compounds 4 and 5 show double-stranded chains constructed by a Cu-(dps)2-Cu bridge while thiocyanate anions act as terminal groups; compound 6 is a mononuclear compound. Moreover, compound 1 shows visible yellow luminescence under UV light irradiation and such phenomenon is mainly attributed to inter-ligand transitions. © 2011 Elsevier Ltd. All rights reserved.
