The structure described by Ce3Ge crystallizes in the tetragonal P4_2/n space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) atoms. In the third Ce site, Ce(3) is bonded in a distorted see-saw-like geometry to four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), and four equivalent Ce(3) atoms. is represented by the CIF card [CIF]
