New Double Salts with Boron-Centered Zirconium Clusters: Syntheses and Structures of Cs[ZrCl5]·Cs2[(Zr6B)X 15] (X = Cl or Cl+I), and Anion Distribution in the Mixed Halide Phase

Two new members of a double salt containing halide supported zirconium octahedra were obtained from solid state reactions. Single-crystal X-ray data refinements established the isotypic compounds as Cs[ZrCl5] ·Cs2[(Zr6B)Cl15] (I) (R?c, Z = 6, a = 12.765(2), c = 34.652(6) A?, R1(F) = 0.0339, wR2(F2) = 0.0770) and the mixed halide Cs[ZrCl5]·Cs2[(Zr 6B)Cl14.57(2)I0.43] (II) (R3?c, Z = 6, a = 12.777(2), c = 34.668(7) A?, R1(F) = 0.0459, wR2(F2) = 0.1279), respectively. The structure contains a network of boron centered [(Zr 6B)Cli12] clusters interbridged three-dimensionally by 6/2 Xa-a atoms at all zirconium vertices (X = Cl, or Cl+1, respectively). Within voids of the cluster network [ZrCl 5]- anions and Cs+ cations are located, allowing for the description as a double salt. The [ZrCl5] - anion (D3h-symmetry) has been found so far only in this structure type. The space requirement of a variety of transition metal complexes is estimated and compared with the volume of the [ZrCl 5]- anion in order to see if other double salts are geometrically possible. Besides the unusual [ZrCl5]- ion the mixed chloride-iodide structure reveals another interesting feature. Contrary to many other structures an ordered chlorine atom substitution by iodine is observed on the cluster interconnecting site. The phase width for Cs[ZrCl5]·Cs2[(Zr6B)Cl 15-XIX] has been found to cover 0 ≤ x ≤ 1.

THERMODYNAMICS OF VAPORIZATION OF ZrI4 IN THE UNIVARIANT REGION: ZIRCONIUM MONOIODIDE/ZIRCONIUM.

The pressures of gaseous ZrI//4 over solid zirconium iodides in the composition range ZrI to Zr were measured by a torsion-effusion method. A univariant region was observed between solids of composition ZrI//1//. //0//5 and Zr. The results extend literature information on the thermodynamics of vaporization in the ZrI//4/Zr region of the Zr-I system.
