Description / Table of Contents:
Zirconium(IV) chloride crystallizes in the monoclinic space group P2/c with a = 6.361, b = 7.407, c = 6.256 Å β = 109.30°, Z = 2. The single crystal X-ray structure analysis shows the structure to consist of an arrangement of ∞1[ZrCl4/2Cl2] zig-zag chains. Within the chains each Zr atom has an octahedral environment; the octahedra are linked through sharing edges, the two terminal Cl ligands being mutually in cis-position. The structure is closely related to those of TcCl4, PtI4 and MoOCl3. The Zr—Cl bond lengths are 2.655 (bridge), 2.498 (bridge) and 2.307 Å (terminal)ZrBr4, HfCl4, and HfBr4 are isostructural with ZrCl4
Notes:
ZrCl4 kristallisiert monoklin in der Raumgruppe P2/c mit a = 6,361, b = 7,407, c = 6,256 Å, β = 109,30°, Z = 2. Die Röntgenstrukturanalyse ergab einen neuen Strukturtyp, in dem ZrCl6-Oktaeder über zwei gemeinsame Kanten zu gewinkelten Ketten ∞1[ZrCl4/2Cl2] verknüpft sind. Die Cl-Atome bilden eine verzerrte kubisch-dichteste Packung. Die jeweils zwei endständigen Cl-Atome pro Oktaeder befinden sich in cis-Stellung zueinander. Die Struktur hat enge Beziehungen zu denen des TcCl4, PtJ4 und MoOCl3. Die Zr—Cl-Bindungsabstände betragen 2,655 (Brücke), 2,498 (Brücke) und 2,307 ÅZrBr4, HfCl4 und HfBr4 sind mit ZrCl4 isotyp.
