The material structure described by InSb crystallizes in the orthorhombic Imm2 space group. In(1) is bonded to two equivalent In(1) and six equivalent Sb(1) atoms to form distorted InIn2Sb6 hexagonal bipyramids that share corners with eight equivalent In(1)In2Sb6 hexagonal bipyramids, edges with twelve equivalent In(1)In2Sb6 hexagonal bipyramids, and edges with twelve equivalent Sb(1)In6Sb2 hexagonal bipyramids. Sb(1) is bonded to six equivalent In(1) and two equivalent Sb(1) atoms to form distorted SbIn6Sb2 hexagonal bipyramids that share corners with eight equivalent Sb(1)In6Sb2 hexagonal bipyramids, edges with twelve equivalent In(1)In2Sb6 hexagonal bipyramids, and edges with twelve equivalent Sb(1)In6Sb2 hexagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
