ZnBiO3 crystallizes in the monoclinic P2_1/c space group. Zn(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with four equivalent Bi(1)O6 octahedra, corners with four equivalent Bi(2)O6 octahedra, and corners with two equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 58-84°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Bi(2)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 52-56°. In the second Bi site, Bi(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 52-56°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1), one Bi(1), and one Bi(2) atom to form distorted corner-sharing OZn2Bi2 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Zn(1), one Bi(1), and one Bi(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Zn(1), one Bi(1), and one Bi(2) atom.
