Materials Data on Sm(ClO)3 by Materials Project
SmOCl3O2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of four hydrogen peroxide molecules and two SmOCl3 sheets oriented in the (0, 0, 1) direction. In each SmOCl3 sheet, Sm is bonded in a 7-coordinate geometry to two equivalent O and five Cl atoms. There are one shorter (2.34 Å) and one longer (2.46 Å) Sm–O bond lengths. There are a spread of Sm–Cl bond distances ranging from 2.61–2.86 Å. O is bonded in a linear geometry to two equivalent Sm atoms. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a water-like geometry to two equivalent Sm atoms. In the second Cl site, Cl is bonded in a single-bond geometry to one Sm atom.
