LaS1.9, CeS1.9, PrS1.9, NdS1.9, and GdS1.9: Five new Lanthanide Polysulfides – Syntheses, Crystal Structures and their Structural Relationship to the ZrSSi Type Crystals of the five new lanthanide polysulfides LaS1.9, CeS1.9, PrS1.9, NdS1.9, and GdS1.9 have been prepared by different synthetic routes. According to X-ray structure analyses, the compounds adopt the tetragonal CeSe1.9 type structure (space
