Bis(quinoline-2-carboxyl-ato-κN,O)lead(II)
Summary
This study reveals lead(II) coordination polymer structures formed by N,O-chelated quinoline-2-carboxylate ligands. The lead atom exhibits distorted geometries due to specific Pb-O interactions, forming layered networks.
Area of Science:
- Inorganic Chemistry
- Crystal Engineering
- Materials Science
Background:
- Lead(II) compounds are known for diverse coordination geometries.
- Quinoline-2-carboxylic acid derivatives are versatile ligands in coordination chemistry.
- Understanding coordination polymers is crucial for developing new materials.
Purpose of the Study:
- To synthesize and characterize a novel lead(II) coordination polymer.
- To elucidate the coordination environment and structural features of the lead atom.
- To investigate the role of Pb-O interactions in forming extended structures.
Main Methods:
- Single-crystal X-ray diffraction analysis.
- Coordination geometry analysis.
- Intermolecular interaction analysis.
Main Results:
- The crystal structure of [Pb(C(10)H(6)NO(2))(2)] was determined.
- The lead(II) atom is N,O-chelated by two quinoline-2-carboxylate ligands, adopting a distorted Ψ-trigonal-bipyramidal geometry.
- Two elongated Pb⋯O interactions contribute to a distorted Ψ-monocapped octahedral geometry and a layered coordination polymer.
Conclusions:
- The coordination behavior of lead(II) with quinoline-2-carboxylate is characterized by specific chelation and longer Pb⋯O contacts.
- These interactions lead to the formation of a unique layered coordination polymer structure.
- The study provides insights into the structural diversity of lead(II) coordination compounds.

02:54Coordination Compounds and Nomenclature
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

00:56Extraction: Advanced Methods
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is formed in...

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
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...

01:17Oxidation of Phenols to Quinones
In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...

01:22EDTA: Chemistry and Properties
Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...
