Materials Data on Eu(InAs)2 by Materials Project
Eu(InAs)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two Eu(InAs)2 sheets oriented in the (0, 0, 1) direction. Eu2+ is bonded to six equivalent As3- atoms to form edge-sharing EuAs6 octahedra. There are four shorter (3.10 Å) and two longer (3.11 Å) Eu–As bond lengths. In2+ is bonded in a trigonal non-coplanar geometry to three equivalent As3- atoms. There are one shorter (2.75 Å) and two longer (2.76 Å) In–As bond lengths. As3- is bonded to three equivalent Eu2+ and three equivalent In2+ atoms to form a mixture of corner and edge-sharing AsEu3In3 octahedra. The corner-sharing octahedral tilt angles are 0°.
