The material structure described by Ce2Rh15Si7 crystallizes in the cubic Pm-3m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a linear geometry to two equivalent Rh(2) and four equivalent Rh(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted cuboctahedral geometry to twelve equivalent Rh(1) atoms. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to one Ce(1), one Ce(2), two equivalent Si(1), and two equivalent Si(2) atoms. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Ce(1) and four equivalent Si(1) atoms. In the third Rh site, Rh(3) is bonded in a 4-coordinate geometry to two equivalent Si(1) and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to three equivalent Rh(1), three equivalent Rh(2), and three equivalent Rh(3) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to four equivalent Rh(1) and four equivalent Rh(3) atoms. is represented by the CIF file [CIF]
