The structure described by Zn(BiO2)4 crystallizes in the triclinic P1 space group. Zn(1) is bonded in a distorted see-saw-like geometry to one O(4), one O(7), and two equivalent O(6) atoms. There are four inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one O(2), one O(7), two equivalent O(4), and two equivalent O(5) atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles range from 51-54°. In the second Bi site, Bi(2) is bonded in a 5-coordinate geometry to one O(1), one O(4), one O(8), and two equivalent O(3) atoms. In the third Bi site, Bi(3) is bonded to one O(1), one O(6), two equivalent O(2), and two equivalent O(8) atoms to form a mixture of edge and corner-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles range from 51-61°. In the fourth Bi site, Bi(4) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(7) atoms to form a mixture of distorted edge and corner-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles range from 54-61°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Bi(2), one Bi(3), and two equivalent Bi(4) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Bi(1) and two equivalent Bi(3) atoms. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one Bi(4) and two equivalent Bi(2) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Zn(1), one Bi(2), and two equivalent Bi(1) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Bi(4) and two equivalent Bi(1) atoms. In the sixth O site, O(6) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one Bi(3) atom. In the seventh O site, O(7) is bonded in a distorted see-saw-like geometry to one Zn(1), one Bi(1), and two equivalent Bi(4) atoms. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one Bi(2) and two equivalent Bi(3) atoms. is represented by the CIF card [CIF]
