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.
