Abstract

Sm2O2I crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sm+2.50+ sites. In the first Sm+2.50+ site, Sm+2.50+ is bonded in a 3-coordinate geometry to three O2- and three equivalent I1- atoms. There are one shorter (2.23 Å) and two longer (2.28 Å) Sm–O bond lengths. There are one shorter (3.38 Å) and two longer (3.55 Å) Sm–I bond lengths. In the second Sm+2.50+ site, Sm+2.50+ is bonded in a 5-coordinate geometry to five O2- and two equivalent I1- atoms. There are a spread of Sm–O bond distances ranging from 2.35–2.42 Å. Both Sm–I bond lengths are 3.43 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four Sm+2.50+ atoms to form a mixture of distorted edge and corner-sharing OSm4 trigonal pyramids. In the second O2- site, O2- is bonded to four Sm+2.50+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra. I1- is bonded in a 5-coordinate geometry to five Sm+2.50+ atoms.
