New Gallium Phosphate Frameworks Containing 1,4-Diaminobutane and 1,5-Diaminopentane: [NH3(CH2)xNH3][Ga4(PO4)4(HPO4)] and [NH3(CH2)xNH3][Ga(PO4)(HPO4)] (x=4 and 5)

Syntheses, Structures, and Ion-Exchange Properties of the Three-Dimensional Framework Uranyl Gallium Phosphates, Cs4[(UO2)2(GaOH)2(PO4)4]·H2O and Cs[UO2Ga(PO4)2]

“…These gallium phosphate chains are formed from fused eight-membered rings of alternating corner-shared GaO 4 and PO 4 tetrahedra as shown in Figure . These types of rings are important building units in gallium phosphate chemistry and have been observed before in compounds such as [Ga(HPO 4 )(PO 4 )(OH)]·[(C 2 H 7 N) 3 N]·H 2 O 6 and [NH 3 (CH 2 ) 4 NH 3 ][Ga(PO 4 )(HPO 4 )] …”

“…Hydrogen bonding between the gallate and phosphate framework and the diamine dications holds the overall structure together. 115…”

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].…”
