Abstract:
The title mononuclear Cu(II) complex, [Cu(C(8)H(5)O(3))(2)(C(10)H(8)N(2))], is comprised of a Cu(II) cation, two 4-formyl-benzoate (L(-)) ligands and a 2,2'-bipyridine (bipy) ligand. The Cu(II) ion and bipy ligand lie on a crystallographic twofold rotation axis; the Cu(II) ion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxyl-ate groups of two L(-) ligands, exhibiting effectively a distorted square-planar geometry. The complex mol-ecules are inter-linked to generate two-dimensional supra-molecular layers in the ab plane, formed by C-H⋯O hydrogen bonds, where the O acceptor is the O atom from the carboxyl-ate group not involved in coordination to the Cu(II) ion. The two-dimensional layers are stacked in a sequence via C-H⋯O hydrogen-bonding inter-actions where the formyl O atom acts as acceptor.

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...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
