Lattice Centering and Coordination Number02:33

Lattice Centering and Coordination Number

9.5K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Valence Bond Theory

8.5K
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...

Atomic Orbitals

33.3K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Area of Science:

  • Nanomaterials Science
  • Materials Chemistry
  • Physical Chemistry

Background:

  • Atomically precise metal nanoclusters (NCs) exhibit superatomic behavior due to quantum confinement.
  • Their unique optical properties enable applications in sensing, bioimaging, and phototherapy.
  • Cluster-assembled materials (CAMs) offer pathways to modify NC photophysical properties by controlling inter- or intracluster interactions.

Purpose of the Study:

  • To synthesize and characterize two distinct CAMs, Au-Zn-Hex and Au-Zn-Rod, using [Au25(p-HMBA)18]- and Zn2+.
  • To investigate the impact of different lattice symmetries on the photophysical properties of these CAMs.
  • To elucidate the structure-property relationships governing luminescence in gold nanocluster-based frameworks.

Main Methods:

  • Synthesis of two distinct cluster-assembled materials (CAMs): Au-Zn-Hex and Au-Zn-Rod.
  • Formation of coordination bonds between [Au25(p-HMBA)18]- (p-H2MBA = 4-mercaptobenzoic acid) and Zn2+ ions.
  • Characterization of luminescence properties, focusing on near-infrared emission intensity.

Main Results:

  • Au-Zn-Rod CAM exhibited a 6-fold higher luminescence intensity in the near-infrared region compared to Au-Zn-Hex.
  • The enhanced luminescence in Au-Zn-Rod is attributed to synergistic inter- and intracluster interactions.
  • These interactions lead to exciton delocalization and structure rigidification at the atomic scale.

Conclusions:

  • Diverse lattice symmetries in cluster-based frameworks can effectively tune photophysical properties.
  • The study provides a deeper understanding of structure-property relationships in gold nanoclusters (Au NCs).
  • This work highlights the potential of CAMs for developing advanced luminescent nanomaterials.
