Materials Data on Nd2Re2Si2C by Materials Project

Abstract

Nd2Re2Si2C crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Nd3+ is bonded in a 2-coordinate geometry to five equivalent Si4- and two equivalent C4- atoms. There are a spread of Nd–Si bond distances ranging from 3.12–3.19 Å. Both Nd–C bond lengths are 2.72 Å. Re3+ is bonded in a single-bond geometry to three equivalent Si4- and one C4- atom. All Re–Si bond lengths are 2.47 Å. The Re–C bond length is 1.96 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Nd3+, three equivalent Re3+, and one Si4- atom. The Si–Si bond length is 2.75 Å. C4- is bonded to four equivalent Nd3+ and two equivalent Re3+ atoms to form edge-sharing CNd4Re2 octahedra.
