Polymeric potassium diaquahexa-mu-cyano-holmium(III)ruthenium(II) dihydrate.
The crystal structure of the title bimetallic cyanide-bridged complex, [K[HoRu(CN)(6)(H(2)O)(2)] x 2H(2)O](n), was determined by means of single-crystal X-ray diffraction techniques. 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. The Ho(III) and K atoms lie at sites with mm symmetry and the Ru atom is at a site with 2/m symmetry.
