Barium cobalt chloride selenite, Ba2CoCl2(SeO3)2

M. G. Johnston and W. T. A. Harrison

Abstract: Hydrothermally synthesized Ba2CoCl2(SeO3)2 contains [001] chains of corner-linked CoO4Cl2 [dav(Co-O) = 2.073  (3)  Å and d(Co-Cl) = 2.544  (2)  Å] octahedra and SeO3 groups [dav(Se-O) = 1.702  (3)  Å]. These chains stack in the [100] direction, with 10-coordinate Ba2+ cations (to seven O and three Cl) binding the chains in the [010] direction. Most of the atoms occupy special positions: Co has site symmetry 2/m and Ba, Se, Cl and one O atom have site symmetry m.
