Ca3FeRhO6 crystallizes in the trigonal R-3c space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Fe(1) is bonded to six equivalent O(1) atoms to form distorted FeO6 pentagonal pyramids that share faces with two equivalent Rh(1)O6 octahedra. Rh(1) is bonded to six equivalent O(1) atoms to form RhO6 octahedra that share faces with two equivalent Fe(1)O6 pentagonal pyramids. O(1) is bonded to four equivalent Ca(1), one Fe(1), and one Rh(1) atom to form a mixture of distorted corner, face, and edge-sharing OCa4FeRh octahedra. The corner-sharing octahedral tilt angles range from 0-69°.
