Materials Data on Sm2Ta2Cl2O7 by Materials Project

Kristin Persson
Sm2Ta2Cl2O7 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sm3+ is bonded in a 9-coordinate geometry to six O2- and three equivalent Cl1- atoms. There are a spread of Sm–O bond distances ranging from 2.37–2.60 Å. There are two shorter (2.87 Å) and one longer (2.88 Å) Sm–Cl bond lengths. Ta5+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TaO6 octahedra. The corner-sharing octahedra tilt...
