The compound described by Ce5GeSb2 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four equivalent Sb(1) atoms. In the second Ce site, Ce(2) is bonded to one Ge(1) and four equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing CeGeSb4 square pyramids. In the third Ce site, Ce(3) is bonded to one Ge(1) and four equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing CeGeSb4 trigonal bipyramids. In the fourth Ce site, Ce(4) is bonded in a 5-coordinate geometry to two equivalent Ge(1) and three equivalent Sb(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to one Ce(2), one Ce(3), two equivalent Ce(1), and four equivalent Ce(4) atoms. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Ce(3), and three equivalent Ce(4) atoms. is represented by the CIF file [CIF]
