Abstract:
The title compounds, [Cu(C(5)H(7)O(2))(2)(C(5)H(6)N(2))], (I), and [Cu(C(5)H(7)O(2))(2)(C(4)H(5)N(3))], (II), were prepared by the reaction of bis(pentane-2,4-dionato-κ(2)O,O')copper(II) with pyridin-2-amine and pyrimidin-2-amine, respectively. From a chemical point of view, it is interesting that no Schiff base formation was observed. The compounds are isostructural, with both having a square-pyramidal coordination of the Cu(II) atom and intramolecular N-H...O hydrogen bonding. The additional N atom of the pyrimidin-2-amine ligand is not involved in hydrogen bonding or in metal coordination. In the crystal structure, chelate rings are involved in π-π interactions and molecules of (I) are linked together via N-H...O hydrogen bonds.

Basicity of Heterocyclic Aromatic Amines
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...
Nomenclature of Alkynes
Acidity 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.
