Materials Data on Eu(SiNi)2 by Materials Project

EuNi2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu3+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Eu–Si bond lengths are 3.13 Å. Ni+2.50+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing NiSi4 tetrahedra. All Ni–Si bond lengths are 2.32 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Eu3+, four equivalent Ni+2.50+, and one Si4- atom. The Si–Si bond length is 2.56 Å.
