The structure described by EuRh3Ge7 crystallizes in the trigonal R-3c space group. Eu(1) is bonded in a 18-coordinate geometry to six equivalent Rh(1) and twelve equivalent Ge(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Eu(1), one Ge(2), and six equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a trigonal planar geometry to three equivalent Rh(1) atoms. In the second Ge site, Ge(1) is bonded in a 3-coordinate geometry to two equivalent Eu(1) and three equivalent Rh(1) atoms. is represented by the CIF file [CIF]
