3. High-Pressure Synthesis and Crystal Structure of the Sulfur-Richest Chromium Sulfide CrS3Composed of Cr(III) and Disulfide Ions

Author

Fukuoka, Hiroshi, Kawata, Naomi, Furuta, Masahiro, Katakami, Yuta, Kimura, Sota, and Inumaru, Kei

Abstract

The new binary chromium sulfide CrS3has been synthesized by reaction of Cr3S4and sulfur mixtures at 800 °C and 13 GPa. CrS3crystallizes in an orthorhombic unit cell with a= 4.6742(7) Å, b= 5.7315(8) Å, c= 10.603(2) Å, and V= 284.873(4) Å3. It has a novel structure composed of Cr2S10edge-shared octahedral dimers, which share all of their corners to form a three-dimensional structure. All of the sulfur atoms form S22–disulfide ions with a S–S distance of 2.063(5) or 2.068(8) Å. The structure of CrS3is a derivative of the crystal structure of marcasite FeS2, in which one in three metal sites of the marcasite structure is vacant in the CrS3structure.

Abstract

The new binary chromium sulfide CrS 3 has been synthesized by reaction of Cr 3 S 4 and sulfur mixtures at 800 °C and 13 GPa. CrS 3 crystallizes in an orthorhombic unit cell with a = 4.6742(7) Å, b = 5.7315(8) Å, c = 10.603(2) Å, and V = 284.873(4) Å 3 . It has a novel structure composed of Cr 2 S 10 edge-shared octahedral dimers, which share all of their corners to form a three-dimensional structure. All of the sulfur atoms form S 2 2- disulfide ions with a S-S distance of 2.063(5) or 2.068(8) Å. The structure of CrS 3 is a derivative of the crystal structure of marcasite FeS 2 , in which one in three metal sites of the marcasite structure is vacant in the CrS 3 structure.
