The material described by ScRh3Si7 crystallizes in the trigonal R-3c space group. Sc(1) is bonded in a 18-coordinate geometry to six equivalent Rh(1) and twelve equivalent Si(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Sc(1), one Si(1), and six equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(2) is bonded in a distorted trigonal planar geometry to two equivalent Sc(1) and three equivalent Rh(1) atoms. In the second Si site, Si(1) is bonded in a trigonal planar geometry to three equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
