Cerous sodium nitrate monohydrate, Na₂Ce(NO₃)₅·H₂O

The title compound, disodium cerium pentanitrate monohydrate, was synthesized from a nitric acid solution of Ce(NO₃)₃·6H₂O and NaNO₃, and its structure has been determined from single-crystal X-ray diffraction data. The structure is built from isolated chains of irregular icosahedral [Ce(NO₃)₆]^3- anions. Na atoms and water mol­ecules are located between the chains. The Na coordination polyhedra, in the form of a square antiprism or a monocapped square antiprism, share common vertices and contribute to the formation of a three-dimensional network. Ten nitrate groups act as bridging ligands.

S1. Comment

The present structure determination is part of a detailed study of the thermal behaviour of Ce^III and Ce^IV nitrate-based precursors of cerium oxide. The cerium(III) compounds M^I₂Ce(NO₃)₅·4H₂O, with M^I = Rb (Audebrand et al., 1996) or NH₄ (Audebrand et al., 1997a), and the similar compound Ag₂Ce(NO₃)₅·H₂O (Audebrand et al., 1997b) have been thoroughly investigated. The family is here extended to include a new mixed Na-based precursor, the title compound, (I), Na₂Ce(NO₃)₅·H₂O.

Compound (I) was identified from powder X-ray diffraction and pattern indexing suggested isostructural properties with Ag₂Ce(NO₃)₅·H₂O, Na₂Nd(NO₃)₅·H₂O (Vigdorchik et al., 1990) and Ce(NO₃)₅(H₃O)₂·H₂O (Guillou et al., 1993). Although the crystals were unstable under ambient conditions, the structure determination has been successful and has confirmed the chemical formula of (I).

The structure of (I) consists of isolated chains parallel to [100] formed by twelve-coordinate Ce polyhedra connected by nitrate groups (Fig. 1), with the alternation Ce1—Ce2—Ce3—Ce2—Ce1. The mean distance between two Ce atoms within a chain is 5.349 (1) Å. The Ce atoms are bonded to six nitrate groups in the form of an irregular icosahedron (Table 1). The mean Ce—O distances [2.65 (5), 2.65 (6) and 2.64 (4) Å for Ce1, Ce2 and Ce3, respectively] are in agreement with the value of 2.65 Å calculated by the bond-valence method (Brown, 1981, 1996).

The Na atoms and the water molecules are located between the chains, with two kinds of alternations of Na atoms parallel to the c axis, Na2—Na4—Na2—Na4 and Na1—Na3—Na1—Na3. The Na atoms are surrounded by eight or nine O atoms, similar to the Ag atoms in Ag₂Ce(NO₃)₅·H₂O, whereas the environments are different in Na₂Nd(NO₃)₅·H₂O. The Na coordination polyhedra are in the form of a distorted monocapped square antiprism for Na1 and Na2 (Fig. 2a), which is less common than the tricapped trigonal prism generally described for a ninefold coordination. Na4 is eight-coordinate in the shape of a distorted square antiprism. For Na3, the coordination is 8 + 1 and the polyhedron can be described as a square antiprism or a monocapped square antiprism. Indeed, the Na3—O93 bond lengh of 3.104 (3) Å is greater than the other Na—O distances [mean value 2.6 (2) Å, Table 1]. Although such a distance is uncommon, the largest Na—O distance considered as a bond is 3.13 Å, according to Donnay & Allmann (1970). The mean Na—O distances [2.7 (2), 2.6 (2), 2.6 (2) and 2.6 (2) Å for Na1, Na2, Na3 and Na4, respectively] are in acceptable agreement with the calculated values (2.62 and 2.57 Å) using the bond-valence method (Brown, 1981, 1996) for Na bonded to nine or eight O atoms. The distortions of each Na coordination polyhedron have been estimated by the calculation of the mean atomic deviations from the least-squares planes.

In the case of the Na4 square antiprism, the mean atomic deviations from the two planes are 0.1315 and 0.0795 Å. The angle between the two planes is 10.59 (9)°. The distances between Na4 and the two planes are 1.109 (3) and 1.369 (3) Å, which shows that Na4 is located near the centre of the square antiprism. For the Na1, Na2 and Na3 monocapped square antiprisms, the mean atomic deviations from the two planes are 0.1017 and 0.0826, 0.0358 and 0.0911, and 0.0080 and 0.0870 Å, respectively. The angles between the two planes are 15.98 (10), 4.71 (15) and 3.30 (14)°, respectively. As expected, the Na atoms are closer to the lower plane, which is close to the capped ninth O atom [distances 0.517 (2), 1.083 (2) and 1.215 (2) Å for Na1, Na2 and Na3, respectively], than to the upper plane [distances 1.687 (2), 1.724 (2) and 1.762 (2) Å for Na1, Na2 and Na3, respectively]. It can be noted that the equivalent isotropic atomic displacement parameter of Na4 is high [0.0473 (5) Ų]. In fact, its displacement ellipsoid is significantly anisotropic in the direction of the chains of Ce icosahedra (Fig. 2). It is worthwhile noting that the equivalent Na atom in the structure of Na₂Nd(NO₃)₅·H₂O and Ag atom in Ag₂Ce(NO₃)₅·H₂O also have high equivalent isotropic atomic displacement parameters.

The Na1 and Na4 coordination polyhedra share common vertices with four other polyhedra, whereas the Na2 and Na3 coordination polyhedra share only five vertices. Such connections generate infinite chains in the three crystallographic directions, leading to a three-dimensional network. In the bc plane, this network forms an irregular honeycomb generating tunnels along the a axis, which are filled by the chains of Ce coordination icosahedra. The ten nitrate groups act as bridging ligands. Two of them (N2 and N3) bridge two Ce coordination icosahedra and connect the two icosahedra to a polyhedron (Na4O₈ or Na1O₉ for N2 and N3, respectively). These nitrate groups (N2 and N3; Fig. 2 b) belong to the class III6b proposed by Leclaire (1979). The nitrate group N10 (class II3c) bridges an icosahedron to the Na1 monocapped antiprism (Fig. 2c). All remaining nitrate groups ensure the connections between an icosahedron and two Na coordination polyhedra, generating the infinite chains of Na polyhedra. They belong either to the class III6b (N1, N4, N5 and N8) or to the class III5 (N6, N7 and N9; Fig. 2 d).

The water molecules, located between the chains of icosahedra, are bonded to the four Na atoms. Although attempts to locate the H atoms failed, it has been possible to distinguish some hydrogen bonds according to the criteria of Baur & Khan (1970). These bonds bridge the Ce coordination polyhedra, and Na atoms and the water molecules contribute significantly to the structural framework.

S2. Experimental

The title compound was obtained from the dissolution in concentrated nitric acid at 423 K (was this under pressure? b.p. 356 K) of analytical grade Ce(NO₃)₃·6H₂O and NaNO₃ taken in the molar ratio 1:2. The solution was evaporated at 313 K until colourless rod-like crystals were formed. The crystals are hygroscopic. The single-crystal used for structure analysis was mounted in a capillary containing dry oil to prevent its decomposition.

S3. Refinement

Nitrate O atoms are denoted O11 to O103, and OW1 and OW2 correspond to water-O atoms. The magnitude of the minimal residual electron density corresponds to the deepest hole located 0.19 Å from atom Ce3.

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.

Data were corrected for Lorentz-polarization effects. The dimensions of the crystal could only be estimated approximately because it was almost invisible in the oil. Consequently, an empirical absorption correction (ψ scans; North et al., 1968) was applied. The low value of R_int for averaging 7649 duplicate intensities supports the view that this procedure has been successful. The structure was solved in the space group P2/c and the Patterson method indicated the positions of three independent Ce atoms close to those reported for Ag₂Ce(NO₃)₅·H₂O. The atomic positions of the Ag compound were then used in the refinement. Anisotropic displacement parameters of all non-H atoms were refined.
