inorganic compounds
LiAsF6.H2O crystallizes with the NaPF6.H2O structure type. [AsF6]− anions, of nearly ideal octahedral geometry (As—F 1.71–1.72 Å), and water molecules form chains via weak FH—O hydrogen bonds. Complex anions and water molecules exhibit a CsCl-like arrangement with the octahedral holes partially occupied by Li cations.
