Abstract
Two cadmium complexes, {[Cd2(2,5-tda)2(ip)4]·4H2O}n (1) and {[Cd2(4,4′-obb)2(ip)2·H2O]·H2O}n (2) (2,5-tda = thiophene-2,5-dicarboxylic acid, 4,4′-obb = 4,4′-oxybisbenzoic acid, ip = 1H-imidazo[4,5-f][1, 10]-phenanthroline), were synthesized and characterized by IR, elemental analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. X-ray analysis revealed that 1 is a dinuclear complex with the 2,5-tda anion connecting two Cd ions in a μ1-η1:η0/μ1-η1:η0 coordination mode. Each dinuclear complex is further connected with neighboring complexes via hydrogen-bonding interactions. Compound 2 displays a 2-D layer structure with opened windows occupied by crystallographic water molecules. The layers are further packed via hydrogen-bonding interactions. Luminescent properties for 1 and 2 are also investigated in the solid state at room temperature.
