Materials Data on MnTc2As by Materials Project
Tc2MnAs is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tc+0.50+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing TcAs4 tetrahedra. All Tc–As bond lengths are 2.60 Å. Mn2+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. All Mn–As bond lengths are 3.00 Å. As3- is bonded in a distorted body-centered cubic geometry to eight equivalent Tc+0.50+ and six equivalent Mn2+ atoms.
