Outline of Final Research Achievements

We have studied the reaction of chromium and sulfur under high-pressure conditions and succeeded in synthesis of a CrS3 powder as a single phase. CrS3 has an anti-ferromagnetic property, and the magnetic structure is analyzed using powder neutron diffraction measurement. We have also investigated the reaction of vanadium and sulfur under high-pressure conditions at higher than 10 GPa. A new binary sulfide was obtained. The compound has a layer structure with eight-fold vanadium atoms coordinated by sulfur atoms, and contains both sulfide and disulfide ions.

Academic Significance and Societal Importance of the Research Achievements

近年地球深部と同等の高圧を発生させることのできる装置の普及によって、高圧下で見いだされた新化合物が興味深い構造や物性を示すという研究成果が、多数発表されている。本研究では、硫化物の系において、新構造を持つ硫化物の合成に成功し、高圧下における遷移金属の配位形態の多様性や、硫黄の重合に関する知見を得ることができた。多彩な化学修飾が可能な構造であることから、物性変換などの研究への展開が期待できる。
