The structure described by BaO is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. Ba(1) is bonded to four equivalent O(1) atoms to form corner-sharing BaO4 tetrahedra. O(1) is bonded to four equivalent Ba(1) atoms to form corner-sharing OBa4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
