Materials Data on Pr2Co3Ge5 by Materials Project

Abstract

Pr2Co3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Pr is bonded in a 1-coordinate geometry to seven Co and ten Ge atoms. There are a spread of Pr–Co bond distances ranging from 3.13–3.44 Å. There are a spread of Pr–Ge bond distances ranging from 2.95–3.29 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 5-coordinate geometry to five equivalent Pr and five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.36–2.44 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to four equivalent Pr and four equivalent Ge atoms. All Co–Ge bond lengths are 2.44 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Pr, two equivalent Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.69 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Pr, three Co, and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Pr and four equivalent Co atoms.
