Materials Data on Sr2PtAu by Materials Project

Sr2PtAu crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 7-coordinate geometry to three equivalent Pt and four equivalent Au atoms. There are one shorter (3.27 Å) and two longer (3.28 Å) Sr–Pt bond lengths. All Sr–Au bond lengths are 3.25 Å. In the second Sr site, Sr is bonded in a 7-coordinate geometry to four equivalent Pt and three equivalent Au atoms. All Sr–Pt bond lengths are 3.25 Å. All Sr–Au bond lengths are 3.28 Å. Pt is bonded in a 9-coordinate geometry to seven Sr and two equivalent Au atoms. Both Pt–Au bond lengths are 2.87 Å. Au is bonded in a 9-coordinate geometry to seven Sr and two equivalent Pt atoms.
