Planar Symmetry

ESR spectra of thianatocopper(II) complexes with imidazole derivatives were studied in ethanolic solutions at 295 and 123 K. Axialsymmetric spectra, attributed to the monomeric complex units, were obtained for the frozen solutions. The bonding parameters were interpreted by using calculated g, Cu-hyperfine, and 14N-ligand hyperfine splitting values. The Cu-N bond parameters indicate a considerable delocalization of the unpaired electron. The values of the isotropic Cu-hyperfine splitting suggest that the deviations from the planar symmetry of the CuN4 units are due to tetrahedral perturbation of the ligand field.

Reactive perforating collagenosis is commonly recognised as an unusual form of transepithelial elimination of collagen and elastin fibres which are extruded through the epidermis in patients with a genetic predisposition or underlying diseases, such as diabetes mellitus or renal diseases. We present the unusual case of an 87-year-old diabetic male with a giant form of reactive perforating collagenosis and review the available literature.
