The material structure described by NaBiTeO5 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms. Bi(1) is bonded in a 7-coordinate geometry to one O(5), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 47°. In the second Te site, Te(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Bi(1), and one Te(2) atom. In the second O site, O(2) is bonded to two equivalent Na(1), one Te(1), and one Te(2) atom to form distorted corner-sharing ONa2Te2 trigonal pyramids. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Bi(1), and one Te(2) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Bi(1), and one Te(1) atom. In the fifth O site, O(5) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Bi(1), and one Te(1) atom. is represented by the CIF file [CIF]
