The crystal structure described by IrSbAs crystallizes in the monoclinic P2_1/c space group. Ir(1) is bonded to three equivalent Sb(1) and three equivalent As(1) atoms to form distorted IrSb3As3 octahedra that share corners with eight equivalent Ir(1)Sb3As3 octahedra, corners with three equivalent Sb(1)AsIr3 tetrahedra, corners with three equivalent As(1)SbIr3 tetrahedra, and edges with two equivalent Ir(1)Sb3As3 octahedra. The corner-sharing octahedral tilt angles range from 53-57°. Sb(1) is bonded to three equivalent Ir(1) and one As(1) atom to form SbAsIr3 tetrahedra that share corners with three equivalent Ir(1)Sb3As3 octahedra, corners with four equivalent Sb(1)AsIr3 tetrahedra, corners with nine equivalent As(1)SbIr3 tetrahedra, and  an edgeedge with one Sb(1)AsIr3 tetrahedra. The corner-sharing octahedral tilt angles range from 71-82°. As(1) is bonded to three equivalent Ir(1) and one Sb(1) atom to form distorted AsSbIr3 tetrahedra that share corners with three equivalent Ir(1)Sb3As3 octahedra, corners with four equivalent As(1)SbIr3 tetrahedra, corners with nine equivalent Sb(1)AsIr3 tetrahedra, and  an edgeedge with one As(1)SbIr3 tetrahedra. The corner-sharing octahedral tilt angles range from 67-73°. is represented by the Crystallographic Information File (CIF) [CIF]
