catena-Poly[[aqua­(ethyl anilinophospho­nato-κO)sodium(I)]-di-μ-aqua]

Abstract

In the title compound, [Na(C8H11NO3P)(H2O)3]n, the sodium cation is octa­hedrally coordinated by five water mol­ecules and one O-bonded ethyl anilinophospho­nate anion. Four of the water mol­ecules bridge to adjacent sodium ions, resulting in an infinite chain of edge-sharing NaO6 polyhedra. A network of N—H(...)O and O—H(...)O hydrogen bonds helps to stabilize the crystal structure.

Comment

Metal phosphates have attracted immense interest during the last two decades for their applications as molecular sieves, absorbents and catalysts (Cheetham et al., 1999). However, the crystal structures of their analogous complex metal phosphate oxynitrides are not well characterized (Fu et al., 2005). As part of our investigation of these materials, the title compound, (I), was prepared and characterised.

The asymmetric unit of (I) is composed of three water molecules, one N-ethoxyphosphorl-phenyl-amide anion and one sodium cation (Fig. 1). The central Na atom has a slightly distorted octahedral coordination mode with six oxygen atoms around it (Table 1). One belongs the N-ethoxyphosphorl-phenyl-amide anion, while all the others are coming from the water molecules. The Na—O bond lengths range from 2.3818 (16) to 2.5014 (18) Å. The phosphorus atom of the ligand adopts a tetrahedral coordination mode and there are three types of P—O bonds and one P—N bond existing in the [PO3N] tetrahetra. The shortest bond lengths of 1.4885 (14) Å (P1—O2) refers to the P=O double bond and the P—O bond lengths of 1.6089 (14)Å is attributed to the P-OEt connection. The longer P—O distance is due to the influence of the –OEt group, according to the literature report (Andrianov et al.,1977). The P—N bond length is 1.6612 (16) Å. The bond angles of O—P—O and O—P—N range from 103.77 (8)–118.43 (8)° and 105.43 (8)–112.93 (8)°, indicating that the tetrahetron is slightly distorted. The connections between the sodium ions and the water molecules result an infinite chain (Figure 2), with the N-ethoxyphosphorl-phenyl-amide anions are appended beside the chains. The phenyl rings have an edge on T shaped stacking geometry and they are overlapped in a parallel displaced mode. A network of N—H···O and O—H···O hydrogen bonds (Table 2) helps to establish the packing.

Experimental

A solution of NaOH (3 mmol) and [Et2NH2][(EtO)PO2(C6H5NH)] (1 mmol) in 10 ml H2O was stirred for 21 h at room temperature. Colourless blocks of (I) were obtained after one week.

Refinement

The H atoms bonded to the O atoms of the water molecules were located in a difference map and refined with distance restraints of O—H = 0.85 (3) Å and isotropic displacement parameters. The other H atoms were positioned geometrically and refined using a riding model approximation, with C—H = 0.93–0.97Å and with Uiso(H)= 1.2Ueq(C) or 1.5Ueq(methyl C).

Special details

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.
