Abstract
The title compound, [ReClO(C18H14OP)(2)], contains severely distorted octahedra with a cis,cis,cis configuration. One of the phenolate O ato ms is trans to the Re=O bond, whereas the two P atoms occupy cis sites . Departure from octahedral geometry can be interpreted in terms of th e steric hindrance between the phosphine groups, the small bite of the P-O chelating agent and the tendency of the Re=O bond to repel The ad jacent bonds. Bond lengths are Re=O 1.686 (4), Re-Cl 2.394(2), Re-P 2. 443(2) and 2.451 (2), and Re-O(phenolate) 2.003 (4) (trans to Re=O) an d 1.987 (4) Angstrom (trans to P).
