Materials Data on Dy(MnSi)2 by Materials Project
DyMn2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Dy3+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All Dy–Si bond lengths are 3.02 Å. Mn+2.50+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing MnSi4 tetrahedra. All Mn–Si bond lengths are 2.36 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Dy3+, four equivalent Mn+2.50+, and one Si4- atom. The Si–Si bond length is 2.48 Å.
