Abstract
The synthesis and structure of the title compound have been determined. Copper is bonded to the dinitro(phenyl)-methane conjugate base by a nitro-group, acting as bidentate ligand. Cu–P and Cu–X bonding are discussed, in comparison with the structures of [M(I)(PPh3)nX] compounds. The Cu–P bond lengths appear to be significantly influenced by the number of bonded phosphine ligands. The crystal structure has been determined by the heavy-atom method from three-dimensional X-ray diffraction data obtained by counter techniques. The structure was refined to R 0.077 for 4 107 independent reflections. Crystals are monoclinic, space group P21/c, with Z= 4 in a unit cell with parameters: a= 9.209(8), b= 14.210(9), c= 30.122(12)Å, β= 104.37(9)°.Keywords
