Summary
Quasi-planar boron hydride and fluoride clusters are more stable than icosahedral ones. This discovery enables the design of novel boron nanostructures from planar building blocks.
Area of Science:
- Computational Chemistry
- Materials Science
- Nanotechnology
Background:
- Boron clusters are fundamental units in nanomaterials.
- Understanding the stability of boron structures is crucial for their application.
Purpose of the Study:
- To investigate the energetic stability of quasi-planar boron hydride (B12Hn) and fluoride (B12Fn) clusters compared to icosahedral forms.
- To explore the stability of fully planar B12F6.
Main Methods:
- Density Functional Theory (DFT) calculations.
- Quantum Monte Carlo (QMC) simulations.
Main Results:
- Quasi-planar B12Hn and B12Fn (n=0-4) structures exhibit greater energetic favorability than their icosahedral counterparts.
- The fully planar B12F6 cluster is found to be more stable than its 3D form.
Conclusions:
- Planar and quasi-planar boron clusters represent stable structural motifs.
- These findings pave the way for designing larger boron-based nanostructures using planar building blocks.

02:42Valence 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...

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

02:42Ionic Crystal Structures
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...

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.
