Abstract

Pr6Ni7Si4 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are four inequivalent Pr sites. In the first Pr site, Pr is bonded in a 2-coordinate geometry to five Ni and four equivalent Si atoms. There are a spread of Pr–Ni bond distances ranging from 2.80–3.53 Å. There are two shorter (3.13 Å) and two longer (3.17 Å) Pr–Si bond lengths. In the second Pr site, Pr is bonded in a 8-coordinate geometry to seven Ni and four Si atoms. There are a spread of Pr–Ni bond distances ranging from 2.82–3.46 Å. There are a spread of Pr–Si bond distances ranging from 3.07–3.28 Å. In the third Pr site, Pr is bonded to eight Ni and four equivalent Si atoms to form a mixture of distorted edge and face-sharing PrSi4Ni8 cuboctahedra. There are a spread of Pr–Ni bond distances ranging from 2.95–3.38 Å. All Pr–Si bond lengths are 3.26 Å. In the fourth Pr site, Pr is bonded in a 7-coordinate geometry to six Ni and four Si atoms. There are a spread of Pr–Ni bond distances ranging from 2.84–3.41 Å. There are a spread of Pr–Si bond distances ranging from 3.07–3.39 Å. There are four inequivalentmore »« less
