Materials Data on SrCd3 by Materials Project
SrCd3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Sr is bonded in a distorted body-centered cubic geometry to fourteen Cd atoms. There are eight shorter (3.26 Å) and six longer (3.76 Å) Sr–Cd bond lengths. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to four equivalent Sr and four equivalent Cd atoms to form a mixture of distorted corner, edge, and face-sharing CdSr4Cd4 tetrahedra. All Cd–Cd bond lengths are 3.26 Å. In the second Cd site, Cd is bonded in a 8-coordinate geometry to six equivalent Sr and eight equivalent Cd atoms.
