Materials Data on Cd5(S2Cl)2 by Materials Project

Abstract

Cd5(S2Cl)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded in a 4-coordinate geometry to four S2- atoms. All Cd–S bond lengths are 2.58 Å. In the second Cd2+ site, Cd2+ is bonded to four S2- atoms to form distorted CdS4 trigonal pyramids that share corners with four CdS2Cl2 trigonal pyramids and edges with two equivalent CdS4 trigonal pyramids. There are a spread of Cd–S bond distances ranging from 2.50–2.70 Å. In the third Cd2+ site, Cd2+ is bonded to four S2- atoms to form distorted CdS4 trigonal pyramids that share corners with four CdS2Cl2 trigonal pyramids and edges with two equivalent CdS4 trigonal pyramids. There are a spread of Cd–S bond distances ranging from 2.50–2.70 Å. In the fourth Cd2+ site, Cd2+ is bonded to two S2- and two equivalent Cl1- atoms to form CdS2Cl2 trigonal pyramids that share corners with four CdS4 trigonal pyramids and an edgeedge with one CdS2Cl2 trigonal pyramid. Both Cd–S bond lengths are 2.50 Å. There are one shorter (2.60 Å) and one longer (2.64 Å) Cd–Cl bond lengths. In the fifth Cd2+ site, Cd2+ is bonded to two S2- and two equivalent Cl1- atoms to form CdS2Cl2 trigonal pyramids that share corners with four CdS4 trigonal pyramids and an edgeedge with one CdS2Cl2 trigonal pyramid. Both Cd–S bond lengths are 2.50 Å. There are one shorter (2.60 Å) and one longer (2.64 Å) Cd–Cl bond lengths. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted see-saw-like geometry to four Cd2+ atoms. In the second S2- site, S2- is bonded in a distorted see-saw-like geometry to four Cd2+ atoms. In the third S2- site, S2- is bonded in a distorted see-saw-like geometry to four Cd2+ atoms. In the fourth S2- site, S2- is bonded in a distorted see-saw-like geometry to four Cd2+ atoms. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in an L-shaped geometry to two equivalent Cd2+ atoms. In the second Cl1- site, Cl1- is bonded in an L-shaped geometry to two equivalent Cd2+ atoms.
