The structure described by ZnBi2O4 crystallizes in the orthorhombic Pbcm space group. Zn(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with ten equivalent Bi(1)O6 pentagonal pyramids and corners with two equivalent Zn(1)O4 tetrahedra. Bi(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form distorted BiO6 pentagonal pyramids that share corners with three equivalent Bi(1)O6 pentagonal pyramids, corners with five equivalent Zn(1)O4 tetrahedra, and edges with five equivalent Bi(1)O6 pentagonal pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Zn(1) and three equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing OZnBi3 tetrahedra. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to four equivalent Bi(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Zn(1) and two equivalent Bi(1) atoms. is represented by the CIF file [CIF]
