Experimental Crystal data

R factor = 0.025; wR factor = 0.041; data-to-parameter ratio = 28.9. 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 single-crystal 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 11[CdTe2/2Te2/1] 4 chains of corner-sharing CdTe4 tetrahedra running parallel [010]. The two Ba 2+ 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.
