Materials Data on Sr(CoSi)2 by Materials Project
SrCo2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All Sr–Si bond lengths are 3.21 Å. Co3+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing CoSi4 tetrahedra. All Co–Si bond lengths are 2.27 Å. Si4- is bonded in a 8-coordinate geometry to four equivalent Sr2+ and four equivalent Co3+ atoms.
