Materials Data on HfTc2Mo by Materials Project

HfMoTc2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two HfMoTc2 ribbons oriented in the (1, 0, 0) direction. Hf4+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Hf–Tc bond lengths are 2.34 Å. Mo2+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Mo–Tc bond lengths are 2.21 Å. Tc3- is bonded in a linear geometry to one Hf4+ and one Mo2+ atom.
