Ti Ti C C
TiC crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two TiC clusters. Ti(1) is bonded in a single-bond geometry to one C(1) atom. The Ti(1)-C(1) bond length is 0.94 Å. C(1) is bonded in a distorted linear geometry to one Ti(1) and one C(1) atom. The C(1)-C(1) bond length is 0.58 Å.
