The crystal structure described by BiSr3O3Cl3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to one O(2), two equivalent O(1), two equivalent Cl(2), and three equivalent Cl(1) atoms. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(1), two equivalent Cl(1), and two equivalent Cl(2) atoms. Bi(1) is bonded in a distorted T-shaped geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Sr(2), two equivalent Sr(1), and one Bi(1) atom to form OSr3Bi tetrahedra that share corners with four equivalent Cl(2)Sr6 octahedra, corners with two equivalent O(2)Sr3Bi tetrahedra,  an edgeedge with one Cl(2)Sr6 octahedra,  an edgeedge with one O(2)Sr3Bi tetrahedra, and edges with two equivalent O(1)Sr3Bi tetrahedra. The corner-sharing octahedral tilt angles range from 28-53°. In the second O site, O(2) is bonded to one Sr(2), two equivalent Sr(1), and one Bi(1) atom to form OSr3Bi tetrahedra that share  a cornercorner with one Cl(2)Sr6 octahedra, corners with four equivalent O(1)Sr3Bi tetrahedra,  an edgeedge with one Cl(2)Sr6 octahedra, edges with two equivalent O(1)Sr3Bi tetrahedra, and  a faceface with one Cl(2)Sr6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to one Sr(2) and three equivalent Sr(1) atoms. In the second Cl site, Cl(2) is bonded to two equivalent Sr(2) and four equivalent Sr(1) atoms to form distorted ClSr6 octahedra that share  a cornercorner with one O(2)Sr3Bi tetrahedra, corners with eight equivalent O(1)Sr3Bi tetrahedra,  an edgeedge with one O(2)Sr3Bi tetrahedra, edges with two equivalent O(1)Sr3Bi tetrahedra, faces with two equivalent Cl(2)Sr6 octahedra, and  a faceface with one O(2)Sr3Bi tetrahedra. is represented by the CIF card [CIF]
