Abstract:
In the title compound, [CoCl2(C11H15N3O2)], the CoII ion is five-coordinated in a strongly distorted square-pyramidal arrangement, with one of the two Cl atoms located in the apical position, and the other Cl atom and the three N-donor atoms of the tridentate methyloxime ligand located in the basal plane. The non-H atoms, except for the Cl atoms, lie on a mirror plane. The two equatorial Co-Noxime distances are almost equal (mean 2.253 A) and are substantially longer than the equatorial Co-Npyridine bond [2.0390 (19) A]. The structure is stabilized by intra- and intermolecular C-H...Cl contacts, which involve one of the methyl C atoms belonging to the methyloxime groups.

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...
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
