Abstract:
In the title compound, [Cu(C₄H₄O₄)(C₁₀H₈N₂)(H₂O)]·2H₂O, the Cu(II) ion displays a slightly distorted square-pyramidal coordination. The water mol-ecule at the apical position shows a long bond [Cu-O = 2.276 (2) Å]. The basal plane is formed by two N atoms of the 2,2'-bipyridine ligand and two carboxyl-ate O atoms from a malonate group. The five-membered chelate ring is almost planar [maximum deviation = -0.006 (2) Å], while the six-membered chelate ring defined by the malonate ligand adopts a distorted boat conformation. In the crystal, Cu(II) complex mol-ecules and lattice water mol-ecules are connected by O-H⋯O and C-H⋯O hydrogen bonds. The crystal packing is further stabilized by π-π inter-actions [centroid-centroid distances = 3.563 (2)-3.828 (2) 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.
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...
