CePt2In7 crystallizes in the tetragonal I4/mmm space group. Ce(1) is bonded to four equivalent In(2) and eight equivalent In(1) atoms to form a mixture of corner and face-sharing CeIn12 cuboctahedra. Pt(1) is bonded in a body-centered cubic geometry to four equivalent In(1) and four equivalent In(3) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and two equivalent Pt(1) atoms. In the second In site, In(2) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) atoms. In the third In site, In(3) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing InPt4 tetrahedra.
