Abstract

In 9,10-phenanthrenesemiquinonatobis(triphenylphosphine)copper(I) (1) the semiquione ligand is oxidized by dibenzoyl disulphide to 9,10-phenanthrenequinone and the complex [(PPh3)Cu(μ-PhCOS)2 Cu(PPh3)2] (3) is formed. Crystals of the complex are triclinic, space group {Mathematical expression}, with cell parameters a=10.712(1), b=12.887(1). c=22.064 Å, α=78.29(1), β=81.88(1), γ=80.83(1), and Z=2. The copper atoms are bridged by the sulphur atoms of the two thiobenzoate groups to form binuclear molecules. The Cu2S2 rhombus is strictly co-planar (Cu-S distances from 2.309 to 2.424 Å). The trigonal planar co-ordination around the one and the tetrahedral coordination around the other copper atom are completed by the phosphorus atoms of the triphenylphosphine molecules (Cu-P distances from 2.238 to 2.287 Å). The copper-copper distance (Cu-Cu=2.620 Å) is 0.6 Å longer than that in metallic copper.
