Samples with various compositions around BaNbSe 3 were prepared. X-ray analysis revealed that the compound is stable at the composition of BaNb 0.80 Se 3 , which formally requires Nb 5Ψ ions (d 0 ). The single-phase region extends to the composition BaNb 0.95 Se 3 . A semiconductor-to-metal transiti
