Ce3Ni2Sn7 crystallizes in the orthorhombic Cmmm 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 two equivalent Ni and twelve Sn atoms. Both Ce–Ni bond lengths are 3.48 Å. There are a spread of Ce–Sn bond distances ranging from 3.26–3.35 Å. In the second Ce site, Ce is bonded in a 10-coordinate geometry to four equivalent Ni and ten Sn atoms. All Ce–Ni bond lengths are 3.62 Å. There are a spread of Ce–Sn bond distances ranging from 3.38–3.51 Å. Ni is bonded in a 5-coordinate geometry to five Ce and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.48–2.54 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a distorted square co-planar geometry to four equivalent Ce atoms. In the second Sn site, Sn is bonded in a 12-coordinate geometry to four Ce and two equivalent Ni atoms. In the third Sn site, Sn is bonded in a 12-coordinate geometry to four Ce and two equivalent Ni atoms. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to six equivalent Ce, one Ni, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.88 Å.
