Diaqua-dichloridobis[quinazolin-4(1H)-one-κN]copper(II)
Abstract:
In the title complex, [CuCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) ion is located on an inversion center and is octahedrally coordinated by two N atoms of the 1H-quinazolin-4-one ligand, two chloride ligands and two aqua ligands. The axial Cu-O distances are significantly longer [2.512 (2) Å], than the Cu-N [2.022 (2) Å] and Cu-Cl [2.3232 (4) Å] distances as a result of Jahn-Teller distortion. Aqua ligands are involved in intra- and inter-molecular hydrogen bonding, and N-H⋯O inter-molecular hydrogen bonds are formed between the organic ligands. In addition, weak π-π inter-actions are observed between the benzene rings of the ligand [centroid-centroid distance = 3.678 (1) Å].

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.
