Materials Data on AlCrTc2 by Materials Project
CrTc2Al crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two CrTc2Al ribbons oriented in the (1, 0, 0) direction. Cr3+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Cr–Tc bond lengths are 2.13 Å. Tc3- is bonded in a linear geometry to one Cr3+ and one Al3+ atom. The Tc–Al bond length is 2.50 Å. Al3+ is bonded in a linear geometry to two equivalent Tc3- atoms.
