Ionic Bonding and Electron Transfer

46.6K
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

Ionic Crystal Structures

18.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Valence Bond Theory

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

VSEPR Theory

Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them. The electrons in the valence shell of a central atom form either bonding...

Area of Science:

  • Organometallic Chemistry
  • Coordination Chemistry
  • Fluorine Chemistry

Background:

  • Molybdenyl compounds are important in catalysis and materials science.
  • Understanding the coordination geometry and stability of these complexes is crucial for their application.
  • Previous studies have focused on different coordination numbers and ligand types.

Purpose of the Study:

  • To synthesize and characterize a new molybdenyl compound with pentafluorophenyl ligands.

Main Methods:

  • Low-temperature synthesis involving organolithium reagents and molybdenyl precursors.
  • Characterization using techniques such as NMR spectroscopy (specifically 19F NMR).
  • Density Functional Theory (DFT) calculations to model related species and determine favored structures.

Main Results:

  • Successful synthesis of the molybdenyl compound [NBu4][MoO2(C6F5)3].
  • Determination of an unusual five-coordinate structure, described as an edge-capped tetrahedron (TE-5), deviating from the Berry-pseudorotation pathway.
  • Demonstration of significant stereochemical stability, with no ligand exchange observed up to 150 °C.
  • DFT calculations confirmed the edge-capped tetrahedron as the most energetically favored structure for related (MoO2X3)(-) species.

Conclusions:

  • The synthesized molybdenyl compound possesses a unique and stable five-coordinate geometry.
  • The edge-capped tetrahedron represents a stable structural motif for (MoO2X3)(-) species.
  • The findings contribute to the understanding of coordination chemistry and structural diversity in molybdenyl complexes.
