Materials Data on BiOsSe by Materials Project
OsBiSe crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Os1- is bonded in a 6-coordinate geometry to three equivalent Bi3+ and three equivalent Se2- atoms. There are a spread of Os–Bi bond distances ranging from 2.76–2.80 Å. There are one shorter (2.47 Å) and two longer (2.50 Å) Os–Se bond lengths. Bi3+ is bonded in a 4-coordinate geometry to three equivalent Os1- and one Se2- atom. The Bi–Se bond length is 2.88 Å. Se2- is bonded to three equivalent Os1- and one Bi3+ atom to form a mixture of distorted corner and edge-sharing SeBiOs3 tetrahedra.
