Abstract: High-quality needle-like CuTaS3 single crystals have been synthesized through a chemical vapor transport(CVT) process. Crystallographic data show the special double chains of edge-sharing TaS6 octahedra. The detailed XPS analysis of CuTaS3 was undertaken and the valence states can be described by Cu+Ta5+3S2–. In addition, CuTaS3 crystals were characterized with Raman spectroscopy.
