Materials Data on PaSiTc2 by Materials Project
PaTc2Si is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Pa3+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. All Pa–Si bond lengths are 3.24 Å. Tc+0.50+ is bonded to four equivalent Si4- atoms to form a mixture of distorted edge and corner-sharing TcSi4 tetrahedra. All Tc–Si bond lengths are 2.80 Å. Si4- is bonded in a 8-coordinate geometry to six equivalent Pa3+ and eight equivalent Tc+0.50+ atoms.
