Low temperature synthesis and structures of alkaline earth metal chalcogenides Ba3Cu4SbS6OH, BaCuSbS3 and BaCu2S2†
Abstract
For the first time, alkaline earth metal multinary chalcogenides Ba3Cu4SbS6OH (1), BaCuSbS3 (2) and BaCu2S2 (3) were synthesized via hydrothermal methods at low temperatures. The structures of these three compounds contain three-dimensional channeled frameworks that are constructed by different types of Cu/S chains.
