Materials Data on AgPPt5 by Materials Project
Pt5AgP crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are two inequivalent Pt+1.20- sites. In the first Pt+1.20- site, Pt+1.20- is bonded to eight equivalent Pt+1.20- and four equivalent Ag1+ atoms to form distorted PtAg4Pt8 cuboctahedra that share corners with four equivalent PtAg4Pt8 cuboctahedra, faces with four equivalent PtAg4Pt8 cuboctahedra, and faces with four equivalent AgPt12 cuboctahedra. All Pt–Pt bond lengths are 2.90 Å. All Pt–Ag bond lengths are 2.80 Å. In the second Pt+1.20- site, Pt+1.20- is bonded in a 4-coordinate geometry to seven Pt+1.20-, two equivalent Ag1+, and two equivalent P5+ atoms. There are four shorter (2.80 Å) and one longer (2.89 Å) Pt–Pt bond lengths. Both Pt–Ag bond lengths are 2.90 Å. Both Pt–P bond lengths are 2.45 Å. Ag1+ is bonded to twelve Pt+1.20- atoms to form AgPt12 cuboctahedra that share corners with four equivalent AgPt12 cuboctahedra, faces with four equivalent PtAg4Pt8 cuboctahedra, and faces with four equivalent AgPt12 cuboctahedra. P5+ is bonded in a body-centered cubic geometry to eight equivalent Pt+1.20- atoms.
