Title: Materials Data on Er2Nb3Ge4 by Materials Project

Abstract

Er2Nb3Ge4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Er–Ge bond distances ranging from 2.85–3.07 Å. There are two inequivalent Nb sites. In the first Nb site, Nb is bonded to six Ge atoms to form distorted corner-sharing NbGe6 octahedra. The corner-sharing octahedra tilt angles range from 46–55°. There are a spread of Nb–Ge bond distances ranging from 2.74–2.85 Å. In the second Nb site, Nb is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Nb–Ge bond distances ranging from 2.65–2.80 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Er, four Nb, and one Ge atom. The Ge–Ge bond length is 2.63 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Er, six Nb, and one Ge atom. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Er, four Nb, and one Ge atom. The Ge–Ge bond length is 2.76 Å.
