Eu(NiAs)2 crystallizes in the tetragonal I4/mmm space group. Eu(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1) and eight equivalent As(1) atoms. Ni(1) is bonded to four equivalent Eu(1) and four equivalent As(1) atoms to form a mixture of distorted corner, edge, and face-sharing NiEu4As4 tetrahedra. As(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent Ni(1) atoms.
