Materials Data on P2Os by Materials Project
OsP2 is zeta iron carbide structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Os2- is bonded to six equivalent P1+ atoms to form a mixture of corner and edge-sharing OsP6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are two shorter (2.36 Å) and four longer (2.40 Å) Os–P bond lengths. P1+ is bonded in a distorted trigonal planar geometry to three equivalent Os2- atoms.
