IrSbS is Spinel-like structured and crystallizes in the orthorhombic Pca2_1 space group. Ir(1) is bonded to three equivalent Sb(1) and three equivalent S(1) atoms to form IrSb3S3 octahedra that share corners with twelve equivalent Ir(1)Sb3S3 octahedra, corners with three equivalent Sb(1)Ir3S tetrahedra, and corners with three equivalent S(1)SbIr3 tetrahedra. The corner-sharing octahedral tilt angles range from 63-64°. Sb(1) is bonded to three equivalent Ir(1) and one S(1) atom to form distorted SbIr3S tetrahedra that share corners with three equivalent Ir(1)Sb3S3 octahedra, corners with six equivalent Sb(1)Ir3S tetrahedra, and corners with nine equivalent S(1)SbIr3 tetrahedra. The corner-sharing octahedral tilt angles range from 77-81°. S(1) is bonded to three equivalent Ir(1) and one Sb(1) atom to form SSbIr3 tetrahedra that share corners with three equivalent Ir(1)Sb3S3 octahedra, corners with six equivalent S(1)SbIr3 tetrahedra, and corners with nine equivalent Sb(1)Ir3S tetrahedra. The corner-sharing octahedral tilt angles range from 77-80°.
