The crystal structure described by Ba4P2O crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to four equivalent P(1) and one O(1) atom. In the second Ba site, Ba(2) is bonded in a 2-coordinate geometry to four equivalent P(1) and two equivalent O(1) atoms. P(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Ba(2) atoms. O(1) is bonded to two equivalent Ba(1) and four equivalent Ba(2) atoms to form corner-sharing OBa6 octahedra. The corner-sharing octahedral tilt angles are 14°. is represented by the CIF file [CIF]
