摘要 : The synthesis and structure of the hydrated mono- and di-potassium salts of benzenepentacarboxylic acid are reported - [K(H4BPC)(H2O2))(2)]center dot(H2O) 1 and [K-2(H3BPC)(H2O)(3)]center dot(H2O) 2 (BPC = benzenepentacarboxylate)... 展开 The synthesis and structure of the hydrated mono- and di-potassium salts of benzenepentacarboxylic acid are reported - [K(H4BPC)(H2O2))(2)]center dot(H2O) 1 and [K-2(H3BPC)(H2O)(3)]center dot(H2O) 2 (BPC = benzenepentacarboxylate). In both instances the structures are complex coordination networks, predominantly containing eta(1) binding modes of the carboxylate and carboxylic acid groups, although bridging (O,O) and (O,O') carboxylates and mu(2)-H2O ligands also feature. Extensive hydrogen bonding is present through the carboxylic acid groups and both coordinated and interstitial water molecules. 收起
