The structure described by MgCeRhIn3 crystallizes in the orthorhombic Pmma space group. Mg(1) is bonded in a distorted linear geometry to two equivalent Rh(1) and four equivalent In(2) atoms. Ce(1) is bonded in a distorted single-bond geometry to one Rh(1) and two equivalent In(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), one Ce(1), two equivalent In(2), and four equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to two equivalent Rh(1) and two equivalent In(2) atoms. In the second In site, In(2) is bonded in a 12-coordinate geometry to four equivalent Mg(1), two equivalent Ce(1), two equivalent Rh(1), and four equivalent In(1) atoms. is represented by the CIF card [CIF]
