CoMnSb is half-Heusler structured and crystallizes in the cubic F-43m space group. Mn(1) is bonded in a body-centered cubic geometry to four equivalent Co(1) and four equivalent Sb(1) atoms. Co(1) is bonded to four equivalent Mn(1) and six equivalent Sb(1) atoms to form distorted CoMn4Sb6 tetrahedra that share corners with four equivalent Sb(1)Mn4Co6 tetrahedra, corners with six equivalent Co(1)Mn4Sb6 tetrahedra, edges with six equivalent Sb(1)Mn4Co6 tetrahedra, and faces with twelve equivalent Co(1)Mn4Sb6 tetrahedra. Sb(1) is bonded to four equivalent Mn(1) and six equivalent Co(1) atoms to form distorted SbMn4Co6 tetrahedra that share corners with four equivalent Co(1)Mn4Sb6 tetrahedra, corners with six equivalent Sb(1)Mn4Co6 tetrahedra, edges with six equivalent Co(1)Mn4Sb6 tetrahedra, and faces with twelve equivalent Sb(1)Mn4Co6 tetrahedra.
