The compound described by BaCoO2 crystallizes in the trigonal P3_121 space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Co(1) is bonded to four equivalent O(1) atoms to form corner-sharing CoO4 tetrahedra. O(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
