Synthesis and characterization of two new metal–organic frameworks with interpenetrated structures and luminescent properties.

Two new metal–organic compounds, [Ag2(HADC)2(bimh)] (1) and [Cd(ADC)(bpp)]n(2) [H2ADC = 1,3-adamantanedicarboxylic acid, bimh = 1,6-bis(2-methyl-imidazole-1-yl)hexane, bpp = 1,3-bis(4-pyridyl)propane], have been synthesized and characterized. Compound1exhibits a discrete symmetric unit with 0D?2D interpenetrating structure. Compound2crystallizes in a chiral space groupP212121and presents a threefold interpenetrated 3D diamondoid network containing three helical chains. Thermal stability, X-ray powder diffraction, and luminescence for1and2are also measured and discussed. [ABSTRACT FROM PUBLISHER]
