Abstract
Ti4Ni2C crystallizes isotypically with Ti4Ni2O, Nb4Ni2C and Ta4Ni2C and can be considered as a partially filled Ti2Ni structure with the C atom occupying an octahedral void.
Single crystals of the intermetallic phase with composition Ti4Ni2C were serendipitously obtained by high-pressure sintering of a mixture with initial chemical composition Ti2Ni. The Ti4Ni2C phase crystallizes in the Fdm space group and can be considered as a partially filled Ti2Ni structure with the C atom occupying an octahedral void. Ti4Ni2C is isotypic with Ti4Ni2O, Nb4Ni2C and Ta4Ni2C, all of which were studied previously by means of powder diffraction.
