TiWMoC3HfNbC2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfNbC2 clusters and two TiWMoC3 clusters. In each HfNbC2 cluster, Hf(1) is bonded in a distorted single-bond geometry to one C(3) and one C(5) atom. The Hf(1)-C(3) bond length is 0.20 Å. The Hf(1)-C(5) bond length is 1.72 Å. Nb(1) is bonded in a single-bond geometry to one C(3) atom. The Nb(1)-C(3) bond length is 0.10 Å. There are two inequivalent C sites. In the first C site, C(3) is bonded in a linear geometry to one Hf(1) and one Nb(1) atom. In the second C site, C(5) is bonded in a single-bond geometry to one Hf(1) atom. In each TiWMoC3 cluster, Ti(1) is bonded in a single-bond geometry to one C(1) atom. The Ti(1)-C(1) bond length is 1.18 Å. W(1) is bonded in a single-bond geometry to one Mo(1) and one C(2) atom. The W(1)-Mo(1) bond length is 1.77 Å. The W(1)-C(2) bond length is 0.16 Å. Mo(1) is bonded in a distorted linear geometry to one W(1) and one C(4) atom. The Mo(1)-C(4) bond length is 1.02 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Ti(1) and one C(2) atom. The C(1)-C(2) bond length is 0.80 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one W(1) and one C(1) atom. In the third C site, C(4) is bonded in a single-bond geometry to one Mo(1) atom.
