The compound 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 7-coordinate geometry to 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 7-coordinate geometry to two equivalent O(1,5); two equivalent O(2); and three equivalent O(3) atoms. Rh(1) is bonded to one O(2); one O(3); two equivalent O(1,5); and two equivalent O(4) atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are four inequivalent O sites. In the first O site, O(1,5) is bonded in a 4-coordinate geometry to 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 edge and corner-sharing OSr5Rh octahedra. The corner-sharing octahedral tilt angles range from 0-6°. 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 edge and corner-sharing OSr5Rh octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Rh(1) atoms. is represented by the CIF card [CIF]
