Materials Data on Er3P4Pd7 by Materials Project

Abstract

Er3Pd7P4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 6-coordinate geometry to ten Pd and six P atoms. There are a spread of Er–Pd bond distances ranging from 3.23–3.47 Å. There are two shorter (2.95 Å) and four longer (2.98 Å) Er–P bond lengths. In the second Er site, Er is bonded in a 12-coordinate geometry to ten Pd and four P atoms. There are a spread of Er–Pd bond distances ranging from 2.96–3.19 Å. There are two shorter (2.93 Å) and two longer (2.97 Å) Er–P bond lengths. There are four inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to four Er, five Pd, and three equivalent P atoms. There are a spread of Pd–Pd bond distances ranging from 2.81–3.06 Å. There are two shorter (2.50 Å) and one longer (2.65 Å) Pd–P bond lengths. In the second Pd site, Pd is bonded to four Er, five Pd, and three P atoms to form a mixture of distorted face, edge, and corner-sharing PdEr4P3Pd5 cuboctahedra. There are one shorter (2.79 Å) and two longer (2.91 Å) Pd–Pd bond lengths. All Pd–P bond lengths are 2.47 Å. In the third Pd site, Pd is bonded to four equivalent Er, six Pd, and two equivalent P atoms to form distorted face-sharing PdEr4P2Pd6 cuboctahedra. Both Pd–P bond lengths are 2.45 Å. In the fourth Pd site, Pd is bonded in a 12-coordinate geometry to five Er, three Pd, and four P atoms. Both Pd–Pd bond lengths are 2.88 Å. There are a spread of Pd–P bond distances ranging from 2.44–2.57 Å. There are two inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to three Er and six Pd atoms. In the second P site, P is bonded in a 9-coordinate geometry to four Er and five Pd atoms.
