Crystal Field Theory - Tetrahedral and Square Planar Complexes02:46

Crystal Field Theory - Tetrahedral and Square Planar Complexes

45.7K
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,...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Ionic Crystal Structures

16.0K
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...

X-ray Crystallography02:18

X-ray Crystallography

24.8K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Area of Science:

  • Supramolecular Chemistry
  • Crystallography
  • Computational Chemistry

Background:

  • Noncovalent chalcogen-chalcogen interactions are increasingly studied.
  • The Cambridge Structural Database (CSD) reveals numerous crystal structures with triangular Ch3 synthons.

Purpose of the Study:

  • To model and analyze triangular interchalcogen interactions in organic molecules.
  • To investigate the role of hydrogen bonding in stabilizing these motifs.
  • To compare Ch3 interactions with halogen bond patterns.

Main Methods:

  • Survey of the Cambridge Structural Database (CSD).
  • Selection and modeling of trimeric complexes of organic divalent chalcogen molecules.
  • Multibody energy calculations.

Main Results:

  • Triangular interchalcogen interactions (Ch3) strengthen in the order S < Se < Te.
  • Hydrogen bonds involving chalcogen centers and substituent H atoms significantly stabilize the Ch3 motifs.
  • The studied complexes exhibit negligible or weak cooperativity.

Conclusions:

  • Triangular chalcogen-chalcogen interactions are a distinct motif stabilized by hydrogen bonding.
  • These interactions differ from the well-established windmill X3 halogen bonding patterns.
  • The findings contribute to understanding noncovalent interactions in chalcogen-containing compounds.
