Ce8Re13B12 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 12-coordinate geometry to three equivalent Ce, nine Re, and six equivalent B atoms. All Ce–Ce bond lengths are 3.09 Å. There are a spread of Ce–Re bond distances ranging from 3.22–3.38 Å. All Ce–B bond lengths are 2.79 Å. In the second Ce site, Ce is bonded in a 6-coordinate geometry to three Ce, nine Re, and six B atoms. Both Ce–Ce bond lengths are 3.11 Å. There are a spread of Ce–Re bond distances ranging from 3.02–3.39 Å. There are a spread of Ce–B bond distances ranging from 2.79–3.14 Å. There are three inequivalent Re sites. In the first Re site, Re is bonded in a cuboctahedral geometry to six equivalent Ce and six equivalent Re atoms. All Re–Re bond lengths are 2.83 Å. In the second Re site, Re is bonded in a 2-coordinate geometry to six Ce and four B atoms. There are two shorter (2.20 Å) and two longer (2.24 Å) Re–B bond lengths. In the third Re site, Re is bonded in a 2-coordinate geometry to five Ce, one Re, and two equivalent B atoms. Both Re–B bond lengths are 2.23 Å. There are two inequivalent B sites. In the first B site, B is bonded in a 9-coordinate geometry to four Ce, two equivalent Re, and three B atoms. There is two shorter (1.83 Å) and one longer (1.87 Å) B–B bond length. In the second B site, B is bonded in a 9-coordinate geometry to four equivalent Ce, four Re, and one B atom.
