NdCoC2 crystallizes in the monoclinic Cc space group. Nd(1) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. Co(1) is bonded in a 4-coordinate geometry to two equivalent C(1) and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 7-coordinate geometry to four equivalent Nd(1), two equivalent Co(1), and one C(2) atom. In the second C site, C(2) is bonded in a 7-coordinate geometry to four equivalent Nd(1), two equivalent Co(1), and one C(1) atom.
