Materials Data on Eu(SiRu)2 by Materials Project
EuRu2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu2+ is bonded in a 8-coordinate geometry to eight equivalent Si4- atoms. All Eu–Si bond lengths are 3.30 Å. Ru3+ is bonded to four equivalent Si4- atoms to form a mixture of distorted edge and corner-sharing RuSi4 tetrahedra. All Ru–Si bond lengths are 2.39 Å. Si4- is bonded in a 4-coordinate geometry to four equivalent Eu2+ and four equivalent Ru3+ atoms.
