Abstract:
In the title compound, [Co(C21H15O3)3], the Co(III) ion is coordinated in a slightly distorted octa-hedral environment by three phenolate O and three benzoyl O atoms from three monoanionic bidentate 2,6-dibenzoyl-4-methyl-phenolate ligands. The dihedral angles between the mean planes of the central phenolate rings and the peripheral phenyl rings are 46.62 (10)/87.06 (9), 60.44 (8)/23.13 (8) and 46.49 (6)/65.29 (6)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions. Mol-ecules are further linked by two π-π [centroid-centroid distances = 3.8612 (14) and 3.9479 (14) Å] and four C-H⋯π inter-actions, forming a three-dimensional network.

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...
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,...

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...
