Polymeric potassium diaquahexa--cyano-holmium(III)ruthenium(II) dihydrate

J. A. Kautz and R. C. Symes

Synopsis: The coordination about the central holmium(III) ion is eightfold in a square-antiprismatic arrangement, while the ruthenium(II) ion is octahedrally coordinated. Channels permeating the crystal lattice contain the potassium cations and two zeolitic water molecules.

Formula: K[HoRu(CN)₆(H₂O)₂]·2H₂O

Redetermination of hydronium perchlorate at 193 and 293 K

A. A. Rahman, A. Usman, S. Chantrapromma and H.-K. Fun

Synopsis: A sample of hydronium perchlorate, H₃O⁺·ClO₄^-, crystallized from ethanol at ambient temperature, was found to be orthorhombic (space group Pnma) at both 193 and 293 K, with no phase transition observed in this temperature range. The hydronium and perchlorate ions lie across a mirror plane but it is not possible to define at either temperature a simple description of the H-atom positions due to the three-dimensional tumbling of the hydronium cation.

Formula: H₃O⁺·ClO₄^-

The correct space group of NaPF₆·H₂O

I. A. Guzei and J. M. Langenhan

Synopsis: The correct space group of crystalline NaPF₆·H₂O has been determined to be Pnna, rather than the group Imma that was originally reported in 1956. The Na⁺ and PF₆^- ions and the water molecules form a three-dimensional network in the solid state.

Formula: NaPF₆·H₂O
