Abstract

(Tetramethylethylenediamine)(9,10-phenanthrenequinone)(9,10- phenanthrenediolato)copper(II), Cu(TMEDA)(PhenCat)-(PhenBQ), has been prepared by treating copper metal with a solution containing TMEDA and 9,10-phenanthrenequinone. Dark green crystals of the complex form in the monoclinic crystal system, space group F21/n, in a unit cell of dimensions a = 14.331 (3) Å, b = 11.079 (3) Å, c = 18.471 (3) Å, β = 101.84 (3)°, V = 2870 (1) Å3, and Z = 4. The coordination geometry about the copper atom is square pyramidal with TMEDA and 9,10-phenanthrenediolate ligands chelated at basal sites and the 9,10-phenanthrenequinone ligand bonded at the apical position through one oxygen atom. The diolate and quinone ligands are paired together at the metal through a charge-transfer interaction. EPR spectra of the complex recorded on solid powder samples and on a single crystal show the marked anisotropy expected of a square pyramidal complex of Cu2+. Several charge distributions are possible for the complex, but this result cor firms the Cu(II)-phenanthrenediolate charge distribution in the solid state.
