Materials Data on HfAlTc2 by Materials Project
HfTc2Al crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two HfTc2Al ribbons oriented in the (1, 0, 0) direction. Hf is bonded in a linear geometry to two equivalent Tc atoms. Both Hf–Tc bond lengths are 2.33 Å. Tc is bonded in a linear geometry to one Hf and one Al atom. The Tc–Al bond length is 2.48 Å. Al is bonded in a linear geometry to two equivalent Tc atoms.
