Materials Data on PrSi2Rh by Materials Project
PrRhSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Pr4+ is bonded in a 10-coordinate geometry to ten Si4- atoms. There are a spread of Pr–Si bond distances ranging from 3.21–3.27 Å. Rh4+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are a spread of Rh–Si bond distances ranging from 2.37–2.45 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a distorted single-bond geometry to six equivalent Pr4+, one Rh4+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.51 Å. In the second Si4- site, Si4- is bonded in a 4-coordinate geometry to four equivalent Pr4+ and four equivalent Rh4+ atoms.
