Materials Data on Eu3Rh4Pb13 by Materials Project

Abstract

Eu3Rh4Pb13 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to four equivalent Rh and twelve equivalent Pb atoms. All Eu–Rh bond lengths are 3.62 Å. There are four shorter (3.57 Å) and eight longer (3.61 Å) Eu–Pb bond lengths. Rh is bonded in a 9-coordinate geometry to three equivalent Eu and six equivalent Pb atoms. All Rh–Pb bond lengths are 2.79 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 9-coordinate geometry to three equivalent Eu, two equivalent Rh, and four Pb atoms. There are a spread of Pb–Pb bond distances ranging from 3.18–3.51 Å. In the second Pb site, Pb is bonded in a cuboctahedral geometry to twelve equivalent Pb atoms.
