Structural features of aluminophosphate materials with

Hydrogen‐Bonded Helices in the Layered Aluminophosphate (C2H8N)2[Al2(HPO4)(PO4)2]

“…The reaction was carried out in the system 1.0 Al(OiPr) 3 -x H 3 PO 4 -y tri-n-propylamine (Pr 3 N)-60 DMF with a fixed DMF volume of 450 mL for each crystallization. Finely ground Al(OiPr) 3 was first dosed into each Teflon hole, then DMF was added by using a Tecan CH Miniprep 75 pipette robot, followed by the addition of Pr 3 N and H 3 PO 4 (85 %). The reaction mixtures were shaken for 2 h for homogenization.…”

“…[2][3][4][5] The aluminophosphate family encompasses a rich structural variety enhanced by the employment of organic amines as structure-directing agent under hydrothermal/ solvothermal conditions. The diverse arrangements of AlO n polyhedral units (n = 4-6) and P(O b ) n (O t ) 4Àn tetrahedral units …”

The systematic enumeration of (4;2)-connected 3D nets related to the tridymite group

“…7(b6)]. Structures derived from this type of net are A1PO4-21 [ATF (Bennett, Cohen, Artioli, Pluth & Smith, 1985)] and AIPOa-EN3 (Bennett, Dytrych, Pluth, Richardson & Smith, 1986). A systematic enumeration of structures made from this type of 2D net with the orientation of the T nodes being either up or down has not yet been done.…”

Four- and six-coordinated Al and an encapsulated isopropylamine species in 7AlPO4.2(C3H7NH2).2H2O

“…Three types of tetrahedral P, one type of tetrahedral A1 and two types of trigonalbipyramidal A1 occur in A1PO4-21 (Bennett, Cohen, Artioli, Pluth & Smith, 1985;Parise & Day 1985), and the 1,3-propanediamine molecule used in the synthesis of crystals studied by Bennett et al (1985) split into three triatomic species encapsulated by the framework. The other aluminophosphates encapsulated intact organic species: A1PO4-12 (Parise, 1984a), A1PO4-EN3 (Parise, 1985), A1PO4-17 (Pluth, Smith & Bennett, 1986). Among the other aluminophosphate structures reviewed by Bennett, Dytrych, Pluth, Richardson & Smith (1986), those of particular interest here are variscite (Kniep, Mootz & Vegas, 1977), metavariscite (Kniep & Mootz, 1973) and a synthetic material A1PO4.1.5H20 (Pluth & Smith, 1985 with an X-ray powder pattern resembling that of H 3 (d 'Yvoire, 1961).…”
