T. Timofte, A. Babai, G. Meyer and A.-V. Mudring

Abstract: The room temperature single-crystal X-ray structure determination of the title compound, PrI₃·9H₂O, better represented as [Pr(OH₂)₉]I₃, shows unequivocally that it belongs to the structure type preferably adopted by hydrates of the lighter rare earth iodides (La-Ho). The praseodymium cation is coordinated by nine water molecules in the form of a tricapped trigonal prism with the metal atom situated on a site of crystallographic symmetry mm2.
