Title: Preparation and Characterization of 7,16-Dibenzoylated Tetraaza[14]Annulene Copper(II) Complexes
Abstract: Abstract The reaction between a tetraaza[14]annulene copper(II) complex and a series of p-substituted benzoyl chlorides gave the corresponding 7,16-dibenzoylated complexes in satisfactory yields. The mass spectra reveal the presence of molecular ion peaks based on the 7,16-dibenzoylated complexes. A strong IR band which is associated with a C=O stretching mode is newly observed in the 1653–1660 cm−1 region upon benzoylation. The electronic spectra for the complexes scarcely change on benzoylation and are similar to those for square-planar complexes. The spin Hamiltonian parameters for the benzoylated copper(II) complexes are analogous to those for the copper(II) complex that is not benzoylated. These copper(II) complexes are approximately square-planar with an unpaired electron in the dx 2-y 2 orbital. Referee I: H. Kula Referee II: K. Kasuga Notes Referee I: H. Kula Referee II: K. Kasuga
