Eu(InAs)2 crystallizes in the monoclinic C2/c space group. Eu(1) is bonded to six equivalent As(1) atoms to form edge-sharing EuAs6 octahedra. In(1) is bonded in a 4-coordinate geometry to one In(1) and three equivalent As(1) atoms. As(1) is bonded to three equivalent Eu(1) and three equivalent In(1) atoms to form a mixture of edge and corner-sharing AsEu3In3 octahedra. The corner-sharing octahedra are not tilted.
Eu(InAs)2 crystallizes in the monoclinic C2/c space group. Eu(1) is bonded to six equivalent As(1) atoms to form edge-sharing EuAs6 octahedra. All Eu(1)-As(1) bond lengths are 3.10 Å. In(1) is bonded in a 4-coordinate geometry to one In(1) and three equivalent As(1) atoms. The In(1)-In(1) bond length is 2.79 Å. There is one shorter (2.71 Å) and two longer (2.72 Å) In(1)-As(1) bond lengths. As(1) is bonded to three equivalent Eu(1) and three equivalent In(1) atoms to form a mixture of edge and corner-sharing AsEu3In3 octahedra. The corner-sharing octahedra are not tilted.
