Abstract
Molybdenum disulfide has been prepared in an unusual poorly crystalline form, termed the "rag" structure, consisting of several stacked but highly folded and disordered S-Mo-S layers. This previously unknown structure demonstrates the flexible and macromolecular nature of the layered transition metal dichalcogenides. The determination of this structure provides a basis for understanding its highly broadened x-ray diffraction pattern and relatively low surface area, and is a starting point for optimizing the catalytic and surface properties of molybdenum disulfide.
