(2,2'-Bipyridine)bis-(3-carboxy-pyrazine-2-carboxyl-ato)copper(II) dihydrate
Abstract:
The title six-coordinated distorted octa-hedral complex, [Cu(C(6)H(3)N(2)O(4))(2)(C(10)H(8)N(2))]·2H(2)O, consists of two 3-carboxy-pyrazine-2-carboxyl-ate anions and one 2,2'-bipyridine ligand. There is a twofold rotation axis positioned at the Cu(II) center. The N atoms of the pyrazine ring occupy the axial positions and two proton-transferred O atoms of tbe acid together with the two N atoms of the 2,2'-bipyridine ligand complete the equatorial plane. The inter-actions existing in the crystal structure are inter-molecular O-H⋯O hydrogen bonds, and C-H⋯O and C-O⋯π inter-actions (O⋯π =3.145 Å, C-O⋯π = 149.75°).

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.

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...
