✦ Synopsis

CeO crystals were grown from purified powder material with a multiple sublimation technique. In addition to crystals with a cubic close-packed (ccp ) arrangement, crystals were found with a hexagonal close-packed (hcp ) structure. Detailed crystallographic evidence is given, including complete refinements, of the room-temperature structures of both polytypes. The radius of the CsO molecule was determined as 3.54 1 ( 1) A, and was found to be equal for both ccp and hcp crystals.
