The compound described by SrCeI4 crystallizes in the triclinic P-1 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent I(1), two equivalent I(2), two equivalent I(3), and two equivalent I(4) atoms. Ce(1) is bonded in a 8-coordinate geometry to two equivalent I(1), two equivalent I(2), two equivalent I(3), and two equivalent I(4) atoms. There are four inequivalent I sites. In the first I site, I(1) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1) and two equivalent Ce(1) atoms. In the second I site, I(2) is bonded to two equivalent Sr(1) and two equivalent Ce(1) atoms to form a mixture of distorted edge and corner-sharing ISr2Ce2 trigonal pyramids. In the third I site, I(3) is bonded to two equivalent Sr(1) and two equivalent Ce(1) atoms to form a mixture of distorted edge and corner-sharing ISr2Ce2 trigonal pyramids. In the fourth I site, I(4) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1) and two equivalent Ce(1) atoms. is represented by the CIF card [CIF]
