Abstract
A new layered gallium phosphate material [(GaPO4)(4)(OH)F.2(C7H11N2)], DMAP-GaPO, has been prepared using 4-dimethylaminopyridine as a structure directing agent (SDA) in the presence of fluorine. The material consists of layers of a zeolite related fluorinated gallium phosphate separated by the SDA. The structure was solved from single crystal X-ray diffraction data collected from an extremely small crystal using synchrotron radiation. The gallophosphate layer consists of a novel type of secondary building unit (SBU) which is related to the double four ring (D4R) cage, one of the most common motifs in gallium phosphate open framework structures. We propose that this unit could be produced by the isomerisation of a D4R prenucleation building unit (PNBU) on condensation. (C) 2001 Elsevier Science Ltd. All rights reserved.
