Materials Data on Pr2Se2O by Materials Project
Pr2Se2O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 1-coordinate geometry to six Se2- and one O2- atom. There are a spread of Pr–Se bond distances ranging from 2.96–3.15 Å. The Pr–O bond length is 2.40 Å. In the second Pr3+ site, Pr3+ is bonded in a 7-coordinate geometry to three Se2- and three equivalent O2- atoms. There are a spread of Pr–Se bond distances ranging from 3.02–3.17 Å. There are one shorter (2.41 Å) and two longer (2.44 Å) Pr–O bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to five Pr3+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to four Pr3+ atoms. O2- is bonded to four Pr3+ atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra.
