Crystal Field Theory - Tetrahedral and Square Planar Complexes02:46

Crystal Field Theory - Tetrahedral and Square Planar Complexes

42.8K
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,...

Coordination Number and Geometry

15.9K
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.

Metallic Solids

18.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Hybridization of Atomic Orbitals I

47.2K
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:

  • Materials Science
  • Condensed Matter Physics
  • Solid-State Chemistry

Background:

  • Existing research on pentagon-based 2D materials has only realized type-2 and type-4 tiling patterns.
  • A systematic classification identifies 15 pentagonal tiling patterns, with most yet to be realized in 2D materials.

Purpose of the Study:

  • To propose and characterize the first stable pentagon-based 2D material featuring the type-1 pentagonal tiling pattern.
  • To investigate the stability and electronic properties of this novel material.

Main Methods:

  • First-principles calculations were employed to predict the material's properties.
  • Phonon renormalization and thermal expansion were considered to assess dynamic stability at elevated temperatures.

Main Results:

  • The novel material, named penta-SrP2, was identified as the first stable 2D material with a type-1 pentagonal tiling.
  • Penta-SrP2 exhibits thermal, mechanical, and dynamic stability above 200 K.
  • The material is a semiconductor with an indirect band gap of 0.96 eV.

Conclusions:

  • The discovery of penta-SrP2 significantly expands the known library of pentagon-based 2D materials.
  • This work offers a new avenue for exploring the high-temperature phase dynamical stability of novel 2D materials.
