The material structure described by InAs crystallizes in the orthorhombic Cmcm space group. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to one As(2) and four equivalent As(1) atoms. In the second In site, In(2) is bonded to two equivalent As(1) and four equivalent As(2) atoms to form a mixture of distorted edge and corner-sharing InAs6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to one In(2), four equivalent In(1), and one As(1) atom. In the second As site, As(2) is bonded to two equivalent In(1) and four equivalent In(2) atoms to form a mixture of edge and corner-sharing AsIn6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. is represented by the CIF card [CIF]
