Materials Data on Er3NiGe2 by Materials Project

Abstract

Er3NiGe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded in a 6-coordinate geometry to one Ni and five Ge atoms. The Er–Ni bond length is 2.81 Å. There are a spread of Er–Ge bond distances ranging from 2.94–3.15 Å. In the second Er site, Er is bonded in a 7-coordinate geometry to two equivalent Ni and five Ge atoms. Both Er–Ni bond lengths are 2.77 Å. There are a spread of Er–Ge bond distances ranging from 2.96–3.58 Å. In the third Er site, Er is bonded in a 8-coordinate geometry to three equivalent Ni and five Ge atoms. There are one shorter (2.92 Å) and two longer (2.99 Å) Er–Ni bond lengths. There are a spread of Er–Ge bond distances ranging from 2.96–3.05 Å. Ni is bonded in a 9-coordinate geometry to six Er and three Ge atoms. There are one shorter (2.47 Å) and two longer (2.49 Å) Ni–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Er and two equivalent Ni atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to eight Er and one Ni atom.
