The material structure described by Sr2RhO4 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to one O(1), one O(5), two equivalent O(3), two equivalent O(4), and three equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to one O(1), one O(4), one O(5), two equivalent O(2), and three equivalent O(3) atoms. Rh(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 23-25°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Rh(1) atoms. In the second O site, O(2) is bonded to two equivalent Sr(2), three equivalent Sr(1), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing OSr5Rh octahedra. The corner-sharing octahedral tilt angles range from 1-8°. In the third O site, O(3) is bonded to two equivalent Sr(1), three equivalent Sr(2), and one Rh(1) atom to form a mixture of distorted edge and corner-sharing OSr5Rh octahedra. The corner-sharing octahedral tilt angles range from 1-9°. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Sr(2), two equivalent Sr(1), and two equivalent Rh(1) atoms. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Rh(1) atoms. is represented by the CIF file [CIF]
