Materials Data on SiTc2As by Materials Project
Tc2SiAs crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Tc2SiAs ribbons oriented in the (1, 0, 0) direction. Tc+0.50- is bonded in a linear geometry to one Si4+ and one As3- atom. The Tc–Si bond length is 2.29 Å. The Tc–As bond length is 2.34 Å. Si4+ is bonded in a linear geometry to two equivalent Tc+0.50- atoms. As3- is bonded in a linear geometry to two equivalent Tc+0.50- atoms.
