TaWC crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaWC clusters. Ta(1) is bonded in a distorted single-bond geometry to one W(1) atom. The Ta(1)-W(1) bond length is 1.94 Å. W(1) is bonded in a distorted linear geometry to one Ta(1) and one C(1) atom. The W(1)-C(1) bond length is 0.59 Å. C(1) is bonded in a single-bond geometry to one W(1) atom.
