โœฆ Synopsis


A new three-dimensional microporous gallophosphate named Mu-8 was hydrothermally synthesized in the presence of N ,N,N H ,N H -tetramethylethylenediamine as organic template. Its structure was determined from X-ray powder data by direct methods and subsequently reยฎned using the Rietveld method. The symmetry is monoclinic, space group P2 1 /c with a 9X513( 9

A and b 114X7ยฐ(3). The structure consists of gallophosphate chains of edge-sharing four rings which are connected through PO 4 tetrahedra and GaO 5 pentahedra. The resulting framework contains channels along [1 0 0] which are delimited by eight-membered ring openings. This material was also characterized by thermal analysis, 13 C and 31 P solid state NMR spectroscopy.

A new gallophosphate was synthesized in aqueous medium using the macrocycle 1,4,8,11-tetraazacyciotetradecane as organic species. The structure was determined by single crystal X-ray diffraction. The symmetry is monoclinic, space group C2/c, a=0.8842(3)nm, b=l.7781(2)nm, c=1.5805(3)nm, 13= 92.05(3)
