Abstract:
The quinquedentate ligand 2,2'-[1,1'-(4-azaheptane-1,7-diyldinitrilo)diethylidyne]diphenol in the title compound, [Cu(C22H27N3O2)], furnishes an N3O2 donor set, which results in a distorted square-pyramidal coordination; the two O and two imine N atoms lie in the basal plane, while the secondary amine N atom of the ligand occupies the axial position. The axial Cu-N bond is 0.33 A longer than the average of the equatorial bonds, and the O atoms are trans. The symmetry of the molecule is lowered by the twist-boat and chair conformations adopted by the two CuNN chelate rings. The complex contains two intramolecular C-H...O interactions, and two molecules of the complex are linked into a dimer by means of moderate N-H...O hydrogen bonds. Spectroscopic evidence supports the presence of hydrogen bonds.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
