Abstract top

The title compound, {(C3H12N2)[Al(OH)(HPO3)2]·H2O}n, has been prepared using a hydrothermal technique and characterized by X-ray diffraction data. The Al atoms are in a distorted octahedral environment. Anions and cations are linked through O-H...O and N-H...O hydrogen bonds.

Comment top

At present, it is well known that a remarkable range of compositions and structures of organically templated inorganic framework solids have been synthesized and studied, because of their potential applications in many fields (Cheetham et al., 1999; Harrison, 2002). There are also lots of studies about the synthesis and characterization of metal phosphates containing V, Zn, Co, etc. (Yamase et al., 1997) and most of the known metal–phosphite compounds have been prepared by various solvent-volatilizing methods. However, only a few organically templated aluminophosphites have been reported. In our present work, we have hydrothermally synthesized and characterized the title compound (Fig. 1).

As seen in Figs. 2 and 3, its structure consists of aluminophosphite lines constructed from AlO6 distorted octahedrons and HPO3 pyramids. Each AlO6 octahedron shares two opposite hydroxy groups with two adjacent AlO6 octahedra to construct an infinte Al—O—Al chain running along the [100] direction. Each P atom shares two oxygen atoms with adjacent Al atoms.

The propane-1,2-diammonium cations and water molecules link Al—O—Al chains via numerous N—H···O and O—H···O hydrogen bonds (Table 1 and Fig. 4).

Experimental top

All reagents were used as purchased without further purification. The synthesis was carried out in a rational way from a mixture of [(CH3)2CHO]3Al, C3N2H10, H3PO3 and H2O in a molar ratio of 1:1:2:250. The mixture was loaded in a Teflon-lined autoclave (23 ml capacity) and was heated at 443k for 4 d under autogenous pressure. The solid product was collected by filtration, washed with water and dried at room temperature. Colorless crystals of the title compound were isolated.

Refinement top

All H atoms were located in a difference Fourier map. Those bonded to C and N were refined using a riding model with C—H ranging from 0.96 to 0.97Å and N—H = 0.89Å and U(H)= 1.2 Ueq(C,N). The other H atoms were isotropically refined. The distance O5—H1 was restrained to 0.82 (2) Å.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
