Materials Data on Ca(SiNi)2 by Materials Project
Ca(NiSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ca2+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Ca–Si bond lengths are 3.08 Å. Ni3+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing NiSi4 tetrahedra. All Ni–Si bond lengths are 2.31 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Ca2+, four equivalent Ni3+, and one Si4- atom. The Si–Si bond length is 2.50 Å.
