Abstract

ZrOsP crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Zr4+ is bonded in a 11-coordinate geometry to six equivalent Os1- and five P3- atoms. There are two shorter (2.92 Å) and four longer (3.04 Å) Zr–Os bond lengths. There are one shorter (2.69 Å) and four longer (2.75 Å) Zr–P bond lengths. Os1- is bonded to six equivalent Zr4+, two equivalent Os1-, and four P3- atoms to form a mixture of distorted corner, edge, and face-sharing OsZr6P4Os2 cuboctahedra. Both Os–Os bond lengths are 2.76 Å. There are two shorter (2.48 Å) and two longer (2.51 Å) Os–P bond lengths. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 9-coordinate geometry to six equivalent Zr4+ and three equivalent Os1- atoms. In the second P3- site, P3- is bonded in a 3-coordinate geometry to three equivalent Zr4+ and six equivalent Os1- atoms.
