Materials Data on Eu(AsRh)2 by Materials Project
Eu(RhAs)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent As atoms. All Eu–Rh bond lengths are 3.54 Å. All Eu–As bond lengths are 3.26 Å. Rh is bonded to four equivalent Eu and four equivalent As atoms to form a mixture of distorted corner, edge, and face-sharing RhEu4As4 tetrahedra. All Rh–As bond lengths are 2.48 Å. As is bonded in a 9-coordinate geometry to four equivalent Eu, four equivalent Rh, and one As atom. The As–As bond length is 2.98 Å.
