Title: Materials Data on Nd2WC2 by Materials Project

Abstract

Nd2WC2 is Ilmenite-like structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Nd3+ is bonded in a 4-coordinate geometry to four C4- atoms. There are a spread of Nd–C bond distances ranging from 2.50–2.67 Å. W2+ is bonded to four C4- atoms to form a mixture of edge and corner-sharing WC4 trigonal pyramids. There are two shorter (2.08 Å) and two longer (2.15 Å) W–C bond lengths. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded to four equivalent Nd3+ and two equivalent W2+ atoms to form a mixture of edge and corner-sharing CNd4W2 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. In the second C4- site, C4- is bonded to four equivalent Nd3+ and two equivalent W2+ atoms to form a mixture of edge and corner-sharing CNd4W2 octahedra. The corner-sharing octahedra tilt angles range from 33–54°.
