As P P Os
OsAsP2 crystallizes in the triclinic P1 space group. Os(1) is bonded in a single-bond geometry to one As(1) and two equivalent P(1) atoms. The Os(1)-As(1) bond length is 0.66 Å. There is one shorter (2.90 Å) and one longer (2.94 Å) Os(1)-P(1) bond length. As(1) is bonded in a single-bond geometry to one Os(1) and two equivalent P(1) atoms. There is one shorter (2.58 Å) and one longer (2.63 Å) As(1)-P(1) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent As(1), and two equivalent P(2) atoms. There is one shorter (1.74 Å) and one longer (2.69 Å) P(1)-P(2) bond length. In the second P site, P(2) is bonded in a 1-coordinate geometry to two equivalent P(1) atoms.
