The structure described by Sr5(AsO4)3Cl crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), four equivalent O(3), and two equivalent Cl(1) atoms. As(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sr(2), two equivalent Sr(1), and one As(1) atom. In the second O site, O(2) is bonded to one Sr(2), two equivalent Sr(1), and one As(1) atom to form distorted OSr3As tetrahedra that share corners with two equivalent Cl(1)Sr6 octahedra and edges with two equivalent O(2)Sr3As tetrahedra. The corner-sharing octahedral tilt angles are 41°. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Sr(2), and one As(1) atom. Cl(1) is bonded to six equivalent Sr(2) atoms to form ClSr6 octahedra that share corners with six equivalent O(2)Sr3As tetrahedra and faces with two equivalent Cl(1)Sr6 octahedra. is represented by the CIF card [CIF]
