Abstract:
In the title complex, [CoBr(C(4)H(7)N(2)O(2))(2)(H(2)O)], a crystallo-graphic mirror plane bis-ects the mol-ecule, perpendicular to the glyoximate ligands. The geometry around the cobalt(III) atom is approximately octa-hedral with the four glyoximate N atoms forming the square base. A bromide ion and the O atom of a water mol-ecule occupy the remaining coordination sites. The N-Co-N bite angles are 82.18 (4) and 80.03 (16)°. The glyoximate moieties form strong intra-molecular O-H⋯O hydrogen bonds. The coordinated water mol-ecule forms an inter-molecular O-H⋯O hydrogen bond with a glyoximate O atom, thereby generating supra-molecular chains parallel to [010].

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.

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...

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...
