Materials Data on PrSiAg by Materials Project
PrAgSi crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Pr3+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. There are four shorter (3.28 Å) and two longer (3.34 Å) Pr–Si bond lengths. Ag1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. There are two shorter (2.49 Å) and one longer (2.53 Å) Ag–Si bond lengths. Si4- is bonded in a 9-coordinate geometry to six equivalent Pr3+ and three equivalent Ag1+ atoms.
