Redetermination of tetraphenylarsonium trans-aquatetrachlorooxorhenate(V) at 100 K

M. Siczek and T. Lis

Abstract: The crystal structure of the title compound, (C₂₄H₂₀As)[ReCl₄O(H₂O)], has been re-examined at 100 K. The complex contains distorted octahedral [ReOCl₄(H₂O)]^- anions, with the Re atom and disordered aqua ligand located on a fourfold axis, and [Ph₄As]⁺ cations with the As atom located on a fourfold inversion axis. In the anion, the terminal Re=O bond, 1.662 (2) Å, is trans to the aqua ligand and the Re-(OH₂) and Re-Cl distances are 2.325 (3) and 2.3479 (5) Å, respectively.
