在800 °C、13 GPa压力下，由Cr 3S 4和硫的混合物反应合成了新的二元硫化铬CrS 3。CrS 3晶体为正交晶系，晶胞参数为a = 4.6742（7）<$，B= 5.7315（8）<$，c= 10.603（2）<$，V = 284.873（4）<$3。它具有由Cr2 S10共边八面体二聚体组成的新颖结构，这些八面体二聚体共享它们的所有角以形成三维结构。所有的硫原子形成S22-二硫离子，S-S距离为2.063（5）或2.068（8）π。CrS 3的结构是白铁矿FeS 2晶体结构的衍生物，其中白铁矿结构的三分之一的金属位置在CrS 3结构中是空缺的。
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 witha= 4.6742(7) Å,b= 5.7315(8) Å,c= 10.603(2) Å, andV= 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.
