Abstract:
A new fluorescent ligand (phi(f) = 0.8 in dioxane), 2-(4'-aminophthalimidomethyl)pyridine (L), has been synthesized. A one-pot synthesis of its copper(I) complex upon reduction of copper(II) is achieved at room temperature. This complex, which has been characterized by X-ray crystallography, shows a linear N-Cu-N geometry with Cu-N bond lengths of 1.89 A. X-ray structure reveals weak Cu...O interactions between copper and one of the imide oxygen atoms of the ligand framework. Additional weak Cu...O interactions between copper and oxygen atoms of the ClO(4)(-) counteranion are detected that lead to a zigzag polymeric chain with alternate ClO(4)(-) and copper ions. A 2-D intermolecular hydrogen bonding network is also observed. This complex is found to be highly inert toward oxidation both in the solid state and in solution.

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.
