Materials Data on PrSiPd by Materials Project
PrPdSi crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded to five Pd and seven Si atoms to form a mixture of distorted edge and face-sharing PrSi7Pd5 cuboctahedra. There are a spread of Pr–Pd bond distances ranging from 3.08–3.49 Å. There are a spread of Pr–Si bond distances ranging from 3.16–3.37 Å. In the second Pr site, Pr is bonded in a 9-coordinate geometry to one Pr, seven Pd, and five Si atoms. The Pr–Pr bond length is 3.53 Å. There are a spread of Pr–Pd bond distances ranging from 3.02–3.47 Å. There are a spread of Pr–Si bond distances ranging from 3.07–3.49 Å. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 5-coordinate geometry to six Pr and three equivalent Si atoms. There are a spread of Pd–Si bond distances ranging from 2.46–2.58 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to six Pr and three Si atoms. There are a spread of Pd–Si bond distances ranging from 2.47–2.58 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 2-coordinate geometry to six Pr, two equivalent Pd, and one Si atom. The Si–Si bond length is 2.38 Å. In the second Si site, Si is bonded in a 4-coordinate geometry to six Pr and four Pd atoms.
