Penta-europium dicadmium penta-anti-monide oxide, Eu(5)Cd(2)Sb(5)O.

Abstract

The title compound, Eu(5)Cd(2)Sb(5)O adopts the Ba(5)Cd(2)Sb(5)F-type structure (Pearson symbol oC52), which contains nine crystallographically unique sites in the asymmetric unit, all on special positions. One Eu, two Sb, and the Cd atom have site symmetry m..; two other Eu, the third Sb and the O atom have site symmetry m2m; the remaining Eu atom has 2/m.. symmetry. Eu atoms fill penta-gonal channels built from corner-sharing CdSb(4) tetra-hedra. The isolated O atom, i.e., an oxide ion O(2-), is located in a distorted tetra-hedral cavity formed by four Eu cations.

Experimental. Selected in the glove box, crystals were put in a Paratone N oil and cut to the desired dimensions. Chosen crystal was mounted on a tip of a glass fiber and quickly onto the goniometer. The crystal was kept under a cold nitrogen stream to protect from ambient conditions.Data collection is performed with four batch runs at φ = 0.00 ° (600 frames), at φ = 90.00 ° (600 frames), at φ = 180.00 ° (600 frames), and at φ = 270.00 (600 frames). Frame width = 0.30 ° in ω. Data are merged and treated with multi-scan absorption corrections.

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.
