“…Reactions using zinc acetate only (no aluminium isopropoxide) gave no solid product and EDX microanalysis shows that the solids prepared in the presence of zinc acetate do not contain zinc. Chippindale and coworkers have observed that in solvothermal systems transition metals appear to improve the crystallinity of the product without becoming a part of it [29,45]. It appears that the same holds true in ionothermal framework synthesis using transition metal acetates.…”

“…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].…”

“…The individual chain units are held together by hydrogen bond interactions involving the amine. It is to be noted that the inorganic chain, [Al(PO )(HPO )], has been observed for the "rst time in AlPOs, though such chain compositions have been observed in edge-shared AlPOs (6b) and gallium phosphates (12). The various hydrogen bond interactions in I are listed in Table 9.…”

“…Recently it has been shown that the reaction of metal ions with amine phosphates o!ers a facile route for the synthesis of open-framework materials (10). Using this method, a layered AlPO possessing tancoite-type structure (11) has been synthesized (5 (12). In this paper we present the synthesis and structures of the one-dimensional phosphates which are rather uncommon compared to the two-and three-dimensional phosphate structures.…”

“…As gallium can readily adopt 4-, 5-, or 6-coordination in oxygen-based polyhedra under these conditions, GaPO frameworks exhibit great structural diversity; many monomeric, chain (1-D), layered (2-D) and three-dimensional (3-D) examples are now known with a number of stoichiometries and Ga:P ratios of 1:3 (1-D (5) The present work is concerned with two classes of such materials; 3-D GaPOs with Ga:P ratio of 4:5 and chain GaPOs with Ga:P ratio of 1:2. Four 3-D phases with Ga:P ratio of 4:5 have previously been characterized: [NH 3 (CH 2 ) 4 NH 3 ][Ga 4 (PO 4 ) 4 (HPO 4 )] (4-and 5-coordinate gallium) (13)) herein referred to as (V), [NH 3 (CH 2 ) 4 [Ga 4 (PO 4 ) 4 (HPO 4 )] Á 0.5H 2 O (4-, 5-and 6-coordinate gallium) (19 (23)), which contain chains of alternating corner sharing GaO 4 and PO 4 tetrahedra.…”
