The compound described by Eu(CrAs)2 crystallizes in the tetragonal I4/mmm space group. Eu(1) is bonded in a distorted body-centered cubic geometry to eight equivalent As(1) atoms. Cr(1) is bonded to four equivalent As(1) atoms to form a mixture of edge and corner-sharing CrAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Cr(1) atoms. is represented by the CIF file [CIF]
