(Methoxo-κO)oxidobis(quinolin-8-olato-κN,O)vanadium(V)
Summary
This study details the crystal structure of a vanadium(V) complex, [V(C(9)H(6)NO)(2)(CH(3)O)O]. The complex features a distorted octahedral geometry around the central vanadium atom, stabilized by quinolin-8-olate ligands.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Vanadium complexes are of interest due to their diverse oxidation states and coordination geometries.
- Quinolin-8-olate is a versatile chelating ligand used in coordination chemistry.
Purpose of the Study:
- To characterize the crystal structure of the novel vanadium(V) complex, [V(C(9)H(6)NO)(2)(CH(3)O)O].
- To investigate the coordination environment and intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, angles, and intermolecular interactions (hydrogen bonds, π-π stacking) was performed.
Main Results:
- The central vanadium(V) atom exhibits a distorted octahedral coordination environment.
- The complex is formed by two bis-chelating quinolin-8-olate ligands, one oxido ligand, and one methoxo ligand.
- Weak intermolecular C-H⋯O hydrogen bonds and C-H⋯π interactions link molecules into chains along the b axis.
Conclusions:
- The study provides a detailed structural description of a new vanadium(V) complex.
- The observed intermolecular interactions offer insights into crystal packing and supramolecular assembly.

Properties of Transition Metals
28.1K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide
11.0K
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate
15.5K
Alkenes can be dihydroxylated using potassium permanganate. The method encompasses the reaction of an alkene with a cold, dilute solution of potassium permanganate under basic conditions to form a cis-diol along with a brown precipitate of manganese dioxide.

Oxidation of Phenols to Quinones
4.5K
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...

Radical Oxidation of Allylic and Benzylic Alcohols
2.2K
Activated manganese(IV) oxide can selectively oxidize allylic and benzylic alcohols via a radical intermediate mechanism. Primary allylic alcohols are oxidized to aldehydes, while secondary allylic alcohols yield ketones. The redox reaction of potassium permanganate with an Mn(II) salt such as manganese sulfate (under either alkaline or acidic conditions), followed by thorough drying, yields the oxidizing agent: activated MnO2. While MnO2 is insoluble in the solvents used for the reaction, the...

Redox Titration: Other Oxidizing and Reducing Agents
1.3K
Besides iodine, other oxidizing or reducing agents can serve as titrants in redox titrations. Common oxidizing titrants include KMnO4, cerium(IV), and K2Cr2O7. The choice of oxidizing titrants depends on factors like stability, cost, analyte strength, and reaction rate between the analyte and titrant. KMnO4 is a strong oxidizing titrant that reduces from Mn(VII) to Mn(II) in a highly acidic solution, simultaneously oxidizing the analyte to a higher oxidation state. In this case, KMnO4 acts as a...
