Materials Data on MnSiTc2 by Materials Project

Tc2MnSi is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tc3- is bonded in a distorted body-centered cubic geometry to four equivalent Mn2+ and four equivalent Si4+ atoms. All Tc–Mn bond lengths are 2.58 Å. All Tc–Si bond lengths are 2.58 Å. Mn2+ is bonded in a body-centered cubic geometry to eight equivalent Tc3- atoms. Si4+ is bonded in a body-centered cubic geometry to eight equivalent Tc3- atoms.

Materials Data on MnSi2Tc by Materials Project

TcMnSi2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two TcMnSi2 ribbons oriented in the (1, 0, 0) direction. Tc3- is bonded in a linear geometry to two equivalent Si atoms. Both Tc–Si bond lengths are 2.35 Å. Mn3+ is bonded in a linear geometry to two equivalent Si atoms. Both Mn–Si bond lengths are 2.37 Å. Si is bonded in a linear geometry to one Tc3- and one Mn3+ atom.
