Abstract:
In the title mononuclear complex, [Cu(C(8)H(7)O(2))Cl(C(12)H(8)N(2))(H(2)O)], the Cu(II) atom is coordinated by one carboxylate O atom from a monodentate 4-methyl-benzoate ligand, two N atoms from the 1,10-phenanthroline ligand, one chloride ion and one water mol-ecule in a square-pyramidal geometry. The crystal structure exhibits inter- and intra-molecular C-H⋯Cl, C-H⋯O, O-H⋯Cl and O-H⋯O hydrogen bonds, as well as C-H⋯π inter-actions of phenanthroline and methyl H atoms towards the π-systems of neighboring 4-methyl-benzoate units and the pyridine rings of the phenanthroline system [centroid-centroid distances are 2.706 (2) and 2.992 (1) Å, respectively].

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
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.
