The crystal structure described by OsP4 is Hausmannite-like structured and crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded to two equivalent P(2) and four equivalent P(1) atoms to form OsP6 octahedra that share corners with four equivalent Os(1)P6 octahedra, corners with four equivalent P(1)P2Os2 tetrahedra, and corners with ten equivalent P(2)P3Os tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent Os(1) and two equivalent P(2) atoms to form PP2Os2 tetrahedra that share corners with two equivalent Os(1)P6 octahedra, corners with six equivalent P(2)P3Os tetrahedra, and corners with eight equivalent P(1)P2Os2 tetrahedra. The corner-sharing octahedral tilt angles range from 64-71°. In the second P site, P(2) is bonded to one Os(1), one P(2), and two equivalent P(1) atoms to form PP3Os tetrahedra that share corners with five equivalent Os(1)P6 octahedra, corners with three equivalent P(2)P3Os tetrahedra, and corners with six equivalent P(1)P2Os2 tetrahedra. The corner-sharing octahedral tilt angles range from 48-80°. is represented by the CIF file [CIF]
