Abstract: The phase with composition Ti 4 Fe 2 C 0.82 O 0.18 , tetratitanium diiron carbide oxide, was unexpectedly synthesized by high-pressure sintering (HPS) of a stoichiometric mixture with nominal composition Ti 2 Fe. The Ti 4 Fe 2 C 0.82 O 0.18 phase crystallizes in the Fd \overline{3} m space group and can be considered as the Ti 2 Fe structure filled with C and O atoms co-occupying the same octahedral void [occupancy ratio 0.82 (7):0.18 (7)]. The Ti 4 Fe 2 C 0.82 O 0.18 phase is isotypic with Ti 4 Ni 2 C and Ti 4 Fe 2 O 0.407 , and is the first example where C and O atoms co-occupy the same site in filled Ti 2 Fe structures.
