Materials Data on SrSn3Pd by Materials Project

SrPdSn3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Sr is bonded in a 12-coordinate geometry to four equivalent Pd and twelve Sn atoms. All Sr–Pd bond lengths are 3.82 Å. There are a spread of Sr–Sn bond distances ranging from 3.60–3.76 Å. Pd is bonded in a 5-coordinate geometry to four equivalent Sr and five Sn atoms. There are one shorter (2.64 Å) and four longer (2.72 Å) Pd–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 1-coordinate geometry to four equivalent Sr, one Pd, and four equivalent Sn atoms. All Sn–Sn bond lengths are 3.07 Å. In the second Sn site, Sn is bonded in a 2-coordinate geometry to four equivalent Sr, two equivalent Pd, and two equivalent Sn atoms.
