OsPTe crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded to three equivalent P(1) and three equivalent Te(1) atoms to form distorted OsTe3P3 octahedra that share corners with eight equivalent Os(1)Te3P3 octahedra, corners with three equivalent Te(1)POs3 tetrahedra, and edges with two equivalent Os(1)Te3P3 octahedra. The corner-sharing octahedral tilt angles range from 55-60°. P(1) is bonded in a 4-coordinate geometry to three equivalent Os(1) and one Te(1) atom. Te(1) is bonded to three equivalent Os(1) and one P(1) atom to form distorted TePOs3 tetrahedra that share corners with three equivalent Os(1)Te3P3 octahedra, corners with four equivalent Te(1)POs3 tetrahedra, and  an edgeedge with one Te(1)POs3 tetrahedra. The corner-sharing octahedral tilt angles range from 72-84°.

The corner-sharing octahedral tilt angles range from 55-60°. There is one shorter (2.43 Å) and two longer (2.44 Å) Os(1)-P(1) bond lengths. There are two shorter (2.61 Å) and one longer (2.63 Å) Os(1)-Te(1) bond length. P(1) is bonded in a 4-coordinate geometry to three equivalent Os(1) and one Te(1) atom. The P(1)-Te(1) bond length is 2.62 Å. Te(1) is bonded to three equivalent Os(1) and one P(1) atom to form distorted TePOs3 tetrahedra that share corners with three equivalent Os(1)Te3P3 octahedra, corners with four equivalent Te(1)POs3 tetrahedra, and  an edgeedge with one Te(1)POs3 tetrahedra.
