Abstract:
Noncovalent interactions, particularly chalcogen bonds (ChBs), have gained prominence in modern chemistry due to their tunability and directionality. We present a pioneering investigation of a d10 metal-involving ChB in triazolylidene Au(I) complexes. The crystal structures reveal the occurrence of intramolecular ChBs between Au(I) and chalcophene substituents positioned on the wingtip of triazolylidene ligands. The strength of these ChB interactions can be effectively modulated by altering the chalcophene moieties and ancillary ligands associated with Au(I). The neutral LAu(I)X complexes exhibit remarkable phosphorescence, with photoluminescence quantum yield (PLQY) reaching up to 70% in the solid state, which is attributed to their rigid structure with intramolecular ChB interactions between the Au and chalcogen atoms. Moreover, density functional theory (DFT) calculations were performed to obtain insights into the nature of the ChB interactions.

02:58Crystal Field Theory - Octahedral Complexes
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...
02:38Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
02:46Crystal Field Theory - Tetrahedral and Square Planar 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,...
