The material described by Bi2O2Te crystallizes in the triclinic P1 space group. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 4-coordinate geometry to four equivalent Te(1), two equivalent O(1), and two equivalent O(2) atoms. In the second Bi site, Bi(2) is bonded in a 4-coordinate geometry to four equivalent Te(1), two equivalent O(1), and two equivalent O(2) atoms. Te(1) is bonded in a body-centered cubic geometry to four equivalent Bi(1) and four equivalent Bi(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Bi(1) and two equivalent Bi(2) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded to two equivalent Bi(1) and two equivalent Bi(2) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
