The compound described by NaBa3BiO6 crystallizes in the trigonal R-3c space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Bi(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. O(1) is bonded to one Na(1), four equivalent Ba(1), and one Bi(1) atom to form a mixture of distorted face, edge, and corner-sharing OBa4NaBi octahedra. The corner-sharing octahedral tilt angles range from 0-63°. is represented by the CIF card [CIF]
