HfVC2 crystallizes in the triclinic P1 space group. Hf(1) is bonded in a 6-coordinate geometry to two equivalent V(1), two equivalent C(1), and two equivalent C(2) atoms. There is one shorter (1.65 Å) and one longer (2.19 Å) Hf(1)-V(1) bond length. There is one shorter (2.43 Å) and one longer (2.61 Å) Hf(1)-C(1) bond length. There is one shorter (2.27 Å) and one longer (2.46 Å) Hf(1)-C(2) bond length. V(1) is bonded in a 6-coordinate geometry to two equivalent Hf(1), two equivalent C(1), and two equivalent C(2) atoms. There is one shorter (2.27 Å) and one longer (2.46 Å) V(1)-C(1) bond length. There is one shorter (2.43 Å) and one longer (2.61 Å) V(1)-C(2) bond length. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 5-coordinate geometry to two equivalent Hf(1), two equivalent V(1), and one C(2) atom. The C(1)-C(2) bond length is 0.57 Å. In the second C site, C(2) is bonded in a 5-coordinate geometry to two equivalent Hf(1), two equivalent V(1), and one C(1) atom.
