The material described by Nd2WC2 is Ilmenite-like structured and crystallizes in the tetragonal P4_2/mnm space group. Nd(1) is bonded in a 4-coordinate geometry to two equivalent C(1) and two equivalent C(2) atoms. W(1) is bonded to two equivalent C(1) and two equivalent C(2) atoms to form a mixture of distorted corner and edge-sharing WC4 trigonal pyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded to four equivalent Nd(1) and two equivalent W(1) atoms to form a mixture of corner and edge-sharing CNd4W2 octahedra. The corner-sharing octahedral tilt angles range from 49-54°. In the second C site, C(2) is bonded to four equivalent Nd(1) and two equivalent W(1) atoms to form a mixture of corner and edge-sharing CNd4W2 octahedra. The corner-sharing octahedral tilt angles range from 32-54°. is represented by the CIF card [CIF]
