Synthesis routes to forming novel materials are oftentimes complicated and indirect. For example, Ta2S5 has only been found as an unwanted byproduct of certain chemical reactions, and its properties were unknown. However, here we demonstrate the grow

Single crystals of Ba2Nb3S8I have been grown using iodine-vapor transport in fused-quartz tubes. The crystals form as flakes with typical areas of 5–10 mm2 and thicknesses of 5–11 μm. The crystal structure was determined using single-crystal x-r

BaNbS 3 is a quasi-one-dimensional metal possessing Nb-Nb chains. Superconductivity was observed at the transition temperature T c = 0.89 K. Specific heat measurements reveal the bulk nature of the superconductivity, and an energy gap E g = 0.245(3)
