چکیده
The magnetic response of valence electrons in doped gold-based M@Au8L8q superatoms (M = Pd, Pt, Ag, Au, Cd, Hg, Ir, and Rh; L PPh3; q 0, +1, +2) is studied by calculating the gauge including magnetically induced currents (GIMIC) framework auxiliary density functional theory. systems include 24 different combinations dopant, total cluster charge, structure (cubic-like or oblate). (both diatropic paratropic) are shown to be sensitive atomic clusters, number superatomic electrons, chemical nature dopant metal. Among cubic-like structures, strongest aromaticity observed Pd- Pt-doped M@Au8L80 clusters. Interestingly, Pt-doping increases as compared a similar all-gold eight-electron system Au9L8+1. With recent implementation GIMIC deMon2k code, we investigated cubic butterfly-like M@Au8 core with single M atom from periods 5 6 groups IX–XII. Surprisingly, doping Pd Pt pure Au case not only near central but encompassing whole metallic core, following aromatic trend > Au. These (Pd, Pt)@Au8 nanoclusters show closed shell 1S21P6 superatom electronic corresponding rule 6n + 2.

Cubic Aromaticity: Fact or Fiction?
Although silicon clusters (Sin) exhibit a diversity of 3-dimensional shapes, a cubic form has not been found to be stable in their small size of 8 Si atoms. While the cubane C8H8 is wellknown for chemists, the octasilacubane Si8H8 possessing a cubic structure has never been synthesized. Using quantum chemical computations we find that doping can lead to stable cubic silicon clusters such as Be@...
متن کاملLigand Protected Gold Alloy Clusters as Superatoms
Density functional study of the experimentally observed ligand-protected gold alloy clusters reveal the same stabilization mechanism as in ligand protected pure AuN: the delocalized s-electron subsystem of a high symmetry metal core exhibits a shell closing. On the basis of this observation it is predicted that the substitution of a single Au atom in the well-known Au25(SR)18 compound with Pd, ...

Electron transfer activities of metal clusters are fundamentally significant and have promising potential in catalysis, charge or energy storage, sensing, biomedicine and other applications. Strong resonance coupling between the metal core energy states and the ligand molecular orbitals has not been established experimentally, albeit exciting progress has been achieved in the composition and st...
متن کاملLigand-stabilized conformations in serum albumin.
Interaction of human serum albumin with anionic azo dyes decreases the susceptibility of the former to hydrolytic attack by five different proteases. By using methyl orange as the ligand, it is shown that the occupation of the two strong binding sites by the dye is necessary and sufficient for this effect. Different ligands decrease the digestibility of albumin to different extents when tested ...
متن کاملLigand channel in pharmacologically stabilized rhodopsin
In the degenerative eye disease retinitis pigmentosa (RP), protein misfolding leads to fatal consequences for cell metabolism and rod and cone cell survival. To stop disease progression, a therapeutic approach focuses on stabilizing inherited protein mutants of the G protein-coupled receptor (GPCR) rhodopsin using pharmacological chaperones (PC) that improve receptor folding and trafficking. In...
