HfTaNbWMoC5 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfTaNbWMoC5 clusters. Hf(1) is bonded in a linear geometry to one C(1) and one C(3) atom. The Hf(1)-C(1) bond length is 1.43 Å. The Hf(1)-C(3) bond length is 1.75 Å. Ta(1) is bonded in a distorted single-bond geometry to one C(3) atom. The Ta(1)-C(3) bond length is 1.12 Å. Nb(1) is bonded in a linear geometry to one Mo(1) and one C(1) atom. The Nb(1)-Mo(1) bond length is 0.91 Å. The Nb(1)-C(1) bond length is 1.66 Å. W(1) is bonded in a distorted single-bond geometry to one C(2) and one C(5) atom. The W(1)-C(2) bond length is 1.59 Å. The W(1)-C(5) bond length is 0.19 Å. Mo(1) is bonded in a distorted linear geometry to one Nb(1) and one C(4) atom. The Mo(1)-C(4) bond length is 1.63 Å. There are five inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Hf(1) and one Nb(1) atom. In the second C site, C(2) is bonded in a linear geometry to one W(1) and one C(4) atom. The C(2)-C(4) bond length is 0.33 Å. In the third C site, C(3) is bonded in a linear geometry to one Hf(1) and one Ta(1) atom. In the fourth C site, C(4) is bonded in a linear geometry to one Mo(1) and one C(2) atom. In the fifth C site, C(5) is bonded in a single-bond geometry to one W(1) atom.
