FeSbAs crystallizes in the orthorhombic Pmn2_1 space group. Fe(1) is bonded to three equivalent Sb(1) and three equivalent As(1) atoms to form distorted FeSb3As3 octahedra that share corners with eight equivalent Fe(1)Sb3As3 octahedra, corners with three equivalent Sb(1)Fe3As tetrahedra, corners with three equivalent As(1)Fe3Sb tetrahedra, and edges with two equivalent Fe(1)Sb3As3 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. Sb(1) is bonded to three equivalent Fe(1) and one As(1) atom to form distorted SbFe3As tetrahedra that share corners with three equivalent Fe(1)Sb3As3 octahedra, corners with six equivalent Sb(1)Fe3As tetrahedra, corners with seven equivalent As(1)Fe3Sb tetrahedra, and  an edgeedge with one As(1)Fe3Sb tetrahedra. The corner-sharing octahedral tilt angles range from 72-76°. As(1) is bonded to three equivalent Fe(1) and one Sb(1) atom to form distorted AsFe3Sb tetrahedra that share corners with three equivalent Fe(1)Sb3As3 octahedra, corners with six equivalent As(1)Fe3Sb tetrahedra, corners with seven equivalent Sb(1)Fe3As tetrahedra, and  an edgeedge with one Sb(1)Fe3As tetrahedra. The corner-sharing octahedral tilt angles range from 70-75°.
