N2 - A hydrothermal reaction of ZnO, HCl, pyromellitic acid, piperazine and water/DMF mixture gave rise to a layered Zn coordination polymer. The structure, determined by single crystal XRD, consists of a network of ZnO4 centers, tetrahedrally coordinated by pyromellitate anions giving rise to a two-dimensional sheet structure. The connectivity resembles a 4-connected network in which each Zn atom is connected to four BTEC anions and each BTEC anion is linked to four Zn2+ ions. The DMF, under hydrothermal conditions, has transformed into dimethylamine. Both the acid and polymer shows photoluminescence with the main emission band for the polymer at about 390 nm (lambda(ex) = 338 nm). Our continuing investigations clearly reveal that it is profitable to explore amine templated metal-organic frameworks. (C) 2004 Elsevier SAS. All rights reserved.
