The Materials Project

SrSeO3 is Potassium chlorate-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.66–3.10 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.72 Å) and two longer (1.73 Å) Se–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Sr2+ and one Se4+ atom to form a mixture of distorted edge and corner-sharing OSr3Se tetrahedra. In the second O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent Sr2+ and one Se4+ atom.
