Materials Data on Nd2Co3Ge5 by Materials Project

Nd2Co3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Nd is bonded in a 1-coordinate geometry to six Ge atoms. There are a spread of Nd–Ge bond distances ranging from 2.93–3.26 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.34–2.43 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to six Ge atoms. There are four shorter (2.43 Å) and two longer (2.75 Å) Co–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to three Co and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.67 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Nd, three Co, and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Nd and four equivalent Co atoms.
