Materials Data on Tc3C by Materials Project
Tc3C is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tc+1.33- is bonded in a 4-coordinate geometry to four equivalent C4+ atoms. There are two shorter (2.52 Å) and two longer (2.67 Å) Tc–C bond lengths. C4+ is bonded to twelve equivalent Tc+1.33- atoms to form a mixture of corner and face-sharing CTc12 cuboctahedra.
