OsAsTe crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded to three equivalent As(1) and three equivalent Te(1) atoms to form distorted OsTe3As3 octahedra that share corners with eight equivalent Os(1)Te3As3 octahedra, corners with three equivalent As(1)TeOs3 tetrahedra, corners with three equivalent Te(1)AsOs3 tetrahedra, and edges with two equivalent Os(1)Te3As3 octahedra. The corner-sharing octahedral tilt angles range from 54-58°. As(1) is bonded to three equivalent Os(1) and one Te(1) atom to form distorted AsTeOs3 tetrahedra that share corners with three equivalent Os(1)Te3As3 octahedra, corners with four equivalent As(1)TeOs3 tetrahedra, corners with nine equivalent Te(1)AsOs3 tetrahedra, and  an edgeedge with one As(1)TeOs3 tetrahedra. The corner-sharing octahedral tilt angles range from 65-74°. Te(1) is bonded to three equivalent Os(1) and one As(1) atom to form distorted TeAsOs3 tetrahedra that share corners with three equivalent Os(1)Te3As3 octahedra, corners with four equivalent Te(1)AsOs3 tetrahedra, corners with nine equivalent As(1)TeOs3 tetrahedra, and  an edgeedge with one Te(1)AsOs3 tetrahedra. The corner-sharing octahedral tilt angles range from 74-82°.
