The novel supramolecular frameworks [Cd(BDC)(phen)(H 2 O)] n ( 2 ) and [Cd 2 (HBTC) 2 (phen) 2 ] 2 n · n Cd(HBTC)(phen) 2 ( 3 ) have been synthesized by reaction of the metal source Cd(phen) 2 (NO 3 ) 2 ( 1 ) with benzene‐1,4‐dicarboxylic acid (H 2 BDC) and benzene‐1,3,5‐tricarboxylic acid (H 3 BTC), respectively in a mixed solution of DMF/C 2 H 5 OH/H 2 O. The three‐dimensional supramolecular structure of 2 is constructed through hydrogen‐bond and aromatic π−π interactions between adjacent metal‐organic polymeric coordination chains. Conversely, interestingly, the supramolecular architecture 3 is formed by extending 1‐D metal‐organic polymeric coordination chains into a 3‐D framework by hydrogen‐bond interactions between polymeric coordination chains and metal‐organic coordination complexes instead of by interchain hydrogen‐bond interactions. Additionally, these three compounds exhibit strong fluorescence at room temperature in the solid state. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
