Pr2Os3 crystallizes in the monoclinic C2/m space group. Pr(1) is bonded in a 7-coordinate geometry to three equivalent Os(1) and four equivalent Os(2) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the second Os site, Os(2) is bonded in a 7-coordinate geometry to four equivalent Pr(1) and three equivalent Os(2) atoms.
Pr2Os3 crystallizes in the monoclinic C2/m space group. Pr(1) is bonded in a 7-coordinate geometry to three equivalent Os(1) and four equivalent Os(2) atoms. There are two shorter (2.90 Å) and one longer (3.07 Å) Pr(1)-Os(1) bond length. There are a spread of Pr(1)-Os(2) bond distances ranging from 3.17-3.43 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 6-coordinate geometry to six equivalent Pr(1) atoms. In the second Os site, Os(2) is bonded in a 7-coordinate geometry to four equivalent Pr(1) and three equivalent Os(2) atoms. There is one shorter (2.30 Å) and two longer (2.47 Å) Os(2)-Os(2) bond lengths.
