The compound described by Sr(InAs)2 crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to six equivalent As(1) atoms to form edge-sharing SrAs6 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 Sr(1) and three equivalent In(1) atoms to form a mixture of corner and edge-sharing AsSr3In3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
