Materials Data on TiAlTc2 by Materials Project

TiTc2Al crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two TiTc2Al ribbons oriented in the (1, 0, 0) direction. Ti3+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Ti–Tc bond lengths are 2.18 Å. Tc3- is bonded in a linear geometry to one Ti3+ and one Al3+ atom. The Tc–Al bond length is 2.51 Å. Al3+ is bonded in a linear geometry to two equivalent Tc3- atoms.
