Materials Data on Ba2NaCu3S5 by Materials Project
Abstract
NaBa2Cu3S5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Na1+ is bonded to six S2- atoms to form distorted NaS6 pentagonal pyramids that share corners with two equivalent NaS6 pentagonal pyramids, corners with eight CuS4 tetrahedra, and edges with four CuS4 tetrahedra. There are a spread of Na–S bond distances ranging from 2.89–3.03 Å. There are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.12–3.41 Å. In the second Ba2+ site, Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.14–3.40 Å. There are two inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with two equivalent NaS6 pentagonal pyramids, corners with four equivalent CuS4 tetrahedra, edges with two equivalent NaS6 pentagonal pyramids, and edges with four CuS4 tetrahedra. There are two shorter (2.40 Å) and two longer (2.46 Å) Cu–S bond lengths. In the second Cu+1.67+ site, Cu+1.67+ is bonded to four S2- atoms to form CuS4 tetrahedra thatmore »
