Resumen en inglés
Two new coordination polymers [Mn(H2btc)(phen)(H2O)2]H2btc · H2O n (1) [H3btc = 1,3,5-benzene tricarboxylic acid, phen = phenanthroline] and [Zn3(btc)2(H2O)8](H2O)4 n (2) have been synthesised and structurally characterised. ...Leer más >
Two new coordination polymers [Mn(H2btc)(phen)(H2O)2]H2btc · H2O n (1) [H3btc = 1,3,5-benzene tricarboxylic acid, phen = phenanthroline] and [Zn3(btc)2(H2O)8](H2O)4 n (2) have been synthesised and structurally characterised. Both the complexes crystallise as 1D chain, which further propagates through ligand-based hydrogen bonding interactions into a 3D supramolecular architecture. Supramolecular framework of 1 is constructed by [Mn(H2btc)(phen)(H2O)2]+ as well as the constituent materials–uncoordinated H2btc− and water molecules. Complex 2 exists as a corrugated chain with both the bridging and terminal Zn2+ ions and each zinc centre is coordinated to four water molecules. Both 1 and 2 are stacked by mutual π-stacking of the ligands and exhibit strong fluorescence emission band at 414 and 400 nm, respectively.< Leer menos
