The compound described by ZnBi2O5 crystallizes in the monoclinic P2_1/c space group. Zn(1) is bonded to one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form distorted ZnO5 trigonal bipyramids that share corners with three equivalent Bi(1)O5 trigonal bipyramids and  an edgeedge with one Zn(1)O5 trigonal bipyramid. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one O(2), one O(3), one O(5), and two equivalent O(1) atoms to form distorted BiO5 trigonal bipyramids that share corners with three equivalent Zn(1)O5 trigonal bipyramids and  an edgeedge with one Bi(1)O5 trigonal bipyramid. In the second Bi site, Bi(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Bi(2) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Zn(1), one Bi(1), and one Bi(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Zn(1), one Bi(1), and one Bi(2) atom. In the fourth O site, O(4) is bonded to two equivalent Zn(1) and two equivalent Bi(2) atoms to form edge-sharing OZn2Bi2 tetrahedra. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Zn(1), one Bi(1), and one Bi(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
