Redetermination of Ba2CdTe3 from single-crystal X-ray data

The previous structure determination of the title compound, dibarium tritelluridocadmate, was based on powder X-ray diffraction data [Wang & DiSalvo (1999). J. Solid State Chem. 148, 464-467]. In the current redetermination from singlecrystal X-ray data, all atoms were refined with anisotropic displacement parameters. The previous structure report is generally confirmed, but with some differences in bond lengths. Ba2CdTe3 is isotypic with Ba2MX3 (M = Mn, Cd; X = S, Se) and features 1 1 [CdTe2/2Te2/1](4-) chains of cornersharing CdTe4 tetrahedra running parallel [010]. The two Ba2+ cations are located between the chains, both within distorted monocapped trigonal-prismatic coordination polyhedra. All atoms in the structure are located on a mirror plane.
