Pr₁₆Mo₂₁O₅₆

Abstract

The structure of hexa­deca­praseodymium henicosa­molybden­um hexa­penta­contaoxide, Pr₁₆Mo₂₁O₅₆, is isotypic with other rare earth representatives of formula type RE ₁₆Mo₂₁O₅₆ (RE = La, Ce, Nd). It is characterized by Mo₁₀O₁₈ ⁱO₈ ^a units (where i = inner and a = apical O atoms) containing biocta­hedral Mo₁₀ clusters and octa­hedral MoO₆ units that share some of their O atoms to form the Mo–O framework. The two independent Mo₁₀ cluster units are centred at Wyckoff positions 2b and 2c and have point-group symmetry . The Mo atom of the MoO₆ unit is likewise situated at an inversion centre (2d). The eight crystallographically different Pr³⁺ cations occupy irregular voids in the framework with coordination numbers to the O atoms varying between 8 and 11.

Comment

Pr₁₆Mo₂₁O₅₆ is isotypic with the Ce₁₆Mo₂₁O₅₆ (Gall & Gougeon, 1993) structure type that has been described in the early 1990s. Subsequently, we also reported the crystal structures of the Nd (Gall & Gougeon, 1998) and La (Gall et al., 1999) members of this formula type. The crystal structure is based on Mo₁₀O₁₈ⁱO₈^a cluster units sharing two or four apical O^a atoms with adjacent MoO₆ octahedra (Figs. 1 and 2). For details of the i- and a-type ligand notation, see: Schäfer & von Schnering (1964). The Mo core of the two crystallographically independent Mo₁₀O₁₈ⁱO₈^a units results from metal edge-sharing of two Mo₆ octahedra. The Mo₁₀(I) cluster formed by the Mo1, Mo2, Mo3, Mo4 and Mo5 atoms are centred on 2b position and the Mo₁₀(II) cluster formed by the Mo6, Mo7, Mo8, Mo9 and Mo10 atoms on 2c position, while the single Mo11 atoms occupy the inversion centres located at the center of four of the six faces (2d position) of the unit-cell. Figure 2 shows the interunit linkage through the apical oxygen atoms between the Mo₁₀(II) clusters and single Mo atoms within the slabs parallel to the bc plane. One can notice that the Mo₁₀(II) clusters are linked to four single Mo atoms, whereas the Mo10(I) ones are only linked to two Mo atoms through oxygen atoms. Consequently, the connectivity formula for the Mo₁₀O₁₈ⁱO₈^a and MoO₆ units can be described as follows: MoO_6/2Mo₁₀O₁₈ⁱO₄^aO_4/2^a-a- Mo₁₀O₁₈ⁱO₆^aO_2/2^a-a. In the Mo₁₀O₁₈ⁱO₈^a cluster units present in Pr₁₆Mo₂₁O₅₆, the Mo—Mo distances range between 2.6435 (5) and 2.8260 (6) Å and between 2.6087 (6) and 2.8525 (7) Å in the Mo₁₀ clusters I and II, respectively. With the exception of Mo5 and Mo10, which are shared by both octahedra forming the Mo10 clusters and are surrounded by four O atoms, all the other Mo atoms are bonded to five O atoms in an approximately square-pyramidal environment (Figs. 3, 4). The Mo—O distances lie between 1.955 (2) and 2.143 (2) Å in cluster I and between 1.939 (2) and 2.175 (2) Å in cluster II. The single Mo atoms are surrounded by six O atoms forming a slightly tetragonally distorted octahedron with four oxygen atoms [2× O5 and 2× O9] at 2.024 (2) and 2.027 (2) Å and two O22 atoms at 2.048 (2) Å. All the eight different Pr³⁺ ions are in general positions and occupy irregularly O-coordinated sites inbetween the Mo₁₀O₁₈ⁱO₈^a units. The coordination numbers of the Pr³⁺ ions vary from 8 to 11 with Pr—O distances spreading over a wide range [2.226 (2) to 3.439 (2) Å].

Experimental

Single crystals of Pr₁₆Mo₂₁O₅₆ were obtained from a mixture of Pr₆O₁₁, MoO₃, and Mo with a nominal composition Pr₂Mo₂O₇. Before use, Mo powder was reduced under H₂ flowing gas at 1273 K during ten hours in order to eliminate any trace of oxygen. The initial mixture (ca 4 g) was cold pressed and loaded into a molybdenum crucible, which was sealed under a low argon pressure using an arc welding system. The charge was heated at the rate of 300 K/h up to 2000 K, the temperature which was held for 18 hours, then cooled at 100 K/h down to 1373 K and finally furnace cooled.

Refinement

The highest peak and the deepest hole are located 0.636 Å and 0.70 Å from Pr1 and Pr2, respectively.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
