“…] along the c axis (15). Hydrogen bonding interactions (represented as dotted lines) between neighboring GaPO chains generate a 'layered' gallophosphate structure.…”

Ionothermal synthesis and crystal structures of metal phosphate chains

“…The first zeotype aluminium phosphates were synthesised by Wilson and co workers in 1982 [2] and over the subsequent years numerous metal phosphate systems have yielded zeolite like frameworks of great interest [3][4][5][6][7][8][9][10][11], for example the extremely large pore cloverite [12] and VSB-1 [13] structures and the catalytically important SAPO-34 [14]. One dimensional metal phosphates based on the same tetrahedral MO 4 and PO 4 building blocks as the zeotypes are also well known in the literature [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] (there are 22 different 1-D aluminium phosphates in the AlPO database) [32]. The first of these to be prepared, a chain of AlO 4 and PO 4 (H 2 ) tetrahedra arranged in corner sharing rings [14], is found in a range of synthetic systems and is one of the basic units for the ''chain to layer'' synthetic mechanism for aluminophosphates proposed by Ozin and co workers [33].…”

Hydrothermal synthesis and structure of the new three-dimensional fluorogallophosphate JGP-4 with a Ga/P ratio of 7/8

“…Recently, a variety of organically templated gallophosphates with the Ga/P ratio of non-unity are beginning to be synthesized that show vast structural and compositional diversities [6]. There are 3-D open-framework GaPOs with the Ga/P ratios of 1/1 [4], 1/2 [7], 4/5 [8], 5/4 [9], a family of 2-D layers with the Ga/P ratios of 1/1 [10], 1/2 [11], 2/3 [12], 6/7 [13] and a series of 1-D chains with the Ga/P ratios of 1/2 [14], 1/3 [15], 3/4 [16], 4/7 [17]. Fe´rey and others have synthesized a series of fluorogallophosphates that show interesting templating effects and structure types with various stoichiometries.…”
