Materials Data on Cr2S3 by Materials Project

Cr2S3 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are eight inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 46–50°. There are three shorter (2.37 Å) and three longer (2.43 Å) Cr–S bond lengths. In the second Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are three shorter (2.38 Å) and three longer (2.41 Å) Cr–S bond lengths. In the third Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are three shorter (2.38 Å) and three longer (2.42 Å) Cr–S bond lengths. In the fourth Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 46–50°. All Cr–S bond lengths are 2.40 Å. In the fifth Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 50°. All Cr–S bond lengths are 2.38 Å. In the sixth Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are three shorter (2.38 Å) and three longer (2.39 Å) Cr–S bond lengths. In the seventh Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 47–48°. All Cr–S bond lengths are 2.38 Å. In the eighth Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Cr–S bond lengths are 2.41 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms. In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms. In the third S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms. In the fourth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms.

背景概述

该数据集提供了由Materials Project生成的Cr2S3材料晶体结构数据，其晶体结构为三方晶系P3空间群，具有三维特征。具体包括八个不等价的Cr3+位点，这些位点通过角共享、边共享或面共享方式与六个S2-原子形成CrS6八面体，键长在2.37-2.43 Å范围内，键角范围为46-50°；同时存在四个不等价的S2-位点，每个位点以矩形跷跷板状几何构型与四个Cr3+原子键合。
