Title: Materials Data on Sr11(CdSb2)6 by Materials Project

Abstract

Sr11Cd6Sb12 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a distorted hexagonal planar geometry to six Sb+2.83- atoms. There are a spread of Sr–Sb bond distances ranging from 3.43–3.61 Å.

The corner-sharing octahedra tilt angles range from 33–48°. There are a spread of Sr–Sb bond distances ranging from 3.30–3.47 Å.
