inorganic compounds
Barium dicobalt(II) bis(phosphate) is built up from BaO12 polyhedra [dav(Ba-O) = 2.995 (1) Å], CoO6 octahedra [dav(Co-O) = 2.098 (2) Å] and PO4 tetrahedra [dav(P-O) = 1.544 (2) Å]. The structure has a strongly layered nature, with Ba2+ cations interspersing infinite sheets of edge-sharing CoO6 groups, which are capped by phosphate tetrahedra. The title compound is isostructural with BaNi2(AsO4)2.
