The material described by Sr(RhO2)4 crystallizes in the monoclinic C2 space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(4) atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 55-61°. In the second Rh site, Rh(2) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 55-61°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Sr(1), one Rh(1), and two equivalent Rh(2) atoms to form a mixture of distorted corner and edge-sharing OSrRh3 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Rh(2) and two equivalent Rh(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1) and three equivalent Rh(2) atoms. In the fourth O site, O(4) is bonded to one Sr(1) and three equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing OSrRh3 trigonal pyramids. is represented by the CIF card [CIF]
