NdCeI4 crystallizes in the monoclinic C2/c space group. Nd(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. Ce(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded to two equivalent Nd(1) and two equivalent Ce(1) atoms to form a mixture of distorted face, corner, and edge-sharing ICe2Nd2 tetrahedra. In the second I site, I(2) is bonded to two equivalent Nd(1) and two equivalent Ce(1) atoms to form a mixture of distorted face, corner, and edge-sharing ICe2Nd2 trigonal pyramids.
NdCeI4 crystallizes in the monoclinic C2/c space group. Nd(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. There are two shorter (3.26 Å) and two longer (3.35 Å) Nd(1)-I(1) bond lengths. There are two shorter (3.29 Å) and two longer (3.45 Å) Nd(1)-I(2) bond lengths. Ce(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. There are two shorter (3.26 Å) and two longer (3.33 Å) Ce(1)-I(1) bond lengths. There are two shorter (3.30 Å) and two longer (3.53 Å) Ce(1)-I(2) bond lengths. There are two inequivalent I sites.
