Summary
This study details a novel copper(II) complex, [Cu(CH(3)COO)(2)(C(7)H(9)NO)(2)], featuring octahedral geometry. The crystal structure reveals specific ligand coordination and intermolecular interactions influencing its layered arrangement.
Area of Science:
- Coordination Chemistry
- Crystallography
- Materials Science
Background:
- Monomeric copper(II) complexes with mixed ligands are of interest for their diverse structural motifs and potential applications.
- Understanding the coordination environment and intermolecular forces is crucial for predicting material properties.
Purpose of the Study:
- To synthesize and characterize a novel copper(II) complex with acetate and 2-(pyridin-2-yl)ethanol ligands.
- To elucidate the coordination geometry, ligand binding modes, and crystal packing of the synthesized complex.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- Spectroscopic methods were used for characterization (though not detailed in the abstract).
Main Results:
- The title compound, [Cu(CH(3)COO)(2)(C(7)H(9)NO)(2)], forms a monomeric complex with octahedral geometry around the Cu(II) atom.
- Acetate ligands coordinate monodentately, while 2-(pyridin-2-yl)ethanol acts as a bidentate ligand via its nitrogen and hydroxyl oxygen atoms.
- An intramolecular hydrogen bond exists between the hydroxyl oxygen and a non-coordinated acetate oxygen. Crystal packing is influenced by C-H⋯O interactions, forming layers.
Conclusions:
- The study successfully synthesized and structurally characterized a unique copper(II) complex.
- The coordination behavior and crystal packing provide insights into the self-assembly of metal-organic compounds.
- The observed C-H⋯O interactions play a significant role in the supramolecular architecture.

01:19α-Hydroxy Ketones via Reductive Coupling of Esters: Acyloin Condensation Overview
The pinacol and McMurry reactions involve the reductive coupling of ketones or aldehydes. Similarly, the bimolecular reductive coupling of two ester molecules in the presence of sodium metal in an aprotic solvent yields an α-hydroxy ketone product. The α-hydroxy ketone is also called acyloin, so the reaction is referred to as ‘acyloin condensation.’
01:07Alkylation of β-Ketoester Enolates: Acetoacetic Ester Synthesis
Acetoacetic ester synthesis is a method to obtain ketones from alkyl halides and β-keto esters. The reaction occurs in the presence of an alkoxide base that abstracts the acidic proton of the β-keto esters. The step results in an enolate ion which is doubly stabilized. The enolate then reacts with an alkyl halide via the SN2 process to produce an alkylated ester intermediate with a new C–C bond. The hydrolysis of the intermediate, followed by acidification, results in an alkylated β-keto acid.
01:14Acid Halides to Ketones: Gilman Reagent
Lithium dialkyl cuprate, also known as Gilman reagents, selectively reduces acid halides to ketones. The acid chloride is treated with Gilman reagent at −78 °C in the presence of ether solution to produce a ketone in good yield.
As shown below, the mechanism proceeds in two steps. First, one of the alkyl groups of the reagent acts as a nucleophile and attacks the acyl carbon of the acid chloride to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen double...

02:42Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
01:09IUPAC Nomenclature of Ketones
Like aldehydes, ketones are named using IUPAC rules; in this case, by replacing “e” in the name of the longest hydrocarbon chain with “one.” In acyclic ketones, the ketonic carbon is given the lowest locant value. For instance, as shown below, a simple five-carbon ketone is named pentan-2-one, instead of pentan-4-one. IUPAC rules also allow the placing of the locant value before the parent name to give an alternate name, 2-pentanone.
01:19Types of Enols and Enolates
Aldehydes and ketones form enols, although only about 1% of the enol is present at the equilibrium for simple monocarbonyl compounds. The enol form is undetectable for acetaldehyde, present as only 1.5 × 10−4 % of acetone, and present as only 1.2% of cyclohexanone. Two kinds of regioisomeric enols are possible for unsymmetrical ketones, and their net composition is 1% at equilibrium. This instability is due to the lower bond energy of C=C than the C=O group. The additional instability of enols...
