Summary: By utilizing relativistic DFT calculations, the study explored the ultrasmall gold-phosphine cluster to investigate similarities and differences among Au, Ag, and Cu in the 1-3 nm size range. The structural distortion is found to be most prominent for gold species, while silver and copper exhibit blue-shift in their optical properties compared to gold.

Summary: This study investigates the use of various N-heterocyclic carbene (NHC) coordinated to coinage metals to generate mechanical bonds for efficient molecular motors. It reveals the nature of mechanical bonds formation in [(NHC-M)2pyz]2+ (M = Cu, Ag, Au; pyz = pyrazine) complexes. The formation of NHC-M pyrazine interaction is mainly determined by the electrostatic characteristics of NHC-M caps and the Lewis basic features of the aromatic pyrazine ring with percentages of 69.9%, 71.8%, and 68.8% for Cu, Ag, and Au species, respectively. The rotational barrier, influenced by the NHC-M pyrazine interaction and structural arrangements, is calculated at 10.2, 8.6, and 6.0 kcal mol-1 for Cu, Ag, and Au, respectively. The relativistic effects on the N-coinage metal bond interaction are crucial in explaining the observed rotational barrier. The theoretical evaluation of mechanical bonds provides valuable insights into the interaction and how structural factors affect the formation of molecular motors, which can guide design and synthesis efforts.

Summary: Recent findings on the enhancement of noble gas-noble metal bonding strength through hydrogen doping have led to the exploration of noble gas inserted neutral compounds involving noble metal trimeric ions. Computational methods were used to investigate the structures, stabilities, and charge distribution of the predicted molecules. The results suggest that the noble gas-metal bond has partial covalent character. The study also indicates that these predicted molecules could potentially be prepared and characterized experimentally.

Summary: This study investigates the role of N-heterocyclic carbene as dative ligands in stabilizing carbon-metal bonds in coinage metal complexes, revealing the significant impact of relativistic effects on bond stability. The heavier the metal, the higher the contribution to bond stabilization, emphasizing the importance of considering relativistic effects in theoretical evaluations of carbon-metal bonds.

Summary: The syntheses and structures of a series of complexes based on the (CC)-C-?-chelated Au(III) unit were reported. The X-ray structures revealed varied dispositions determined by the different coordination modes of Ag(I) or Cu(I). The complexes showed bright photoluminescence in the solid state and in PMMA films, dominated by (IL)-I-3((CC)-C-?) transitions with indirect effects from the rest of the molecules.

Summary: The synthesis of copper and gold complexes containing homoleptic carbonyl cations is reported, along with structural data on rare trimetallic complexes. Silver and gold cations exhibit linear structures, while copper cations show a bending angle due to strong interaction with anions. Fe(CO)(5) ligands adopt different orientations in the cations, with distinct symmetry for each metal cation. Bond dissociation energies and orbital interactions between the ligands and metal cations are also analyzed.

Summary: In this study, a high throughput computational approach was used to investigate the adsorption and separation properties of C8-C12 hydrocarbons on a tube-shaped metallo-cavitand, pillarplex (PPX). The results showed that Cu-PPX exhibited a higher binding affinity with the hydrocarbons compared to Ag-PPX. The thermodynamic properties and simulations demonstrated that Cu-PPX and Au-PPX were the ideal hosts for storing hydrocarbons at ambient conditions.

Summary: The CM-L and CM+-L complexes of three coinage metals, CM = Cu, Ag, and Au, with three key ligands, L = CO, N-2, and H-2, were investigated. Various quantum chemical methods were used to calculate the equilibrium geometries and interaction energies. The results showed challenging situations for some neutral species, with significant differences in geometry and/or harmonic vibrational wavenumbers in some cases. Molecular orbital diagrams, atomic charges, and orbital contour plots were presented to gain insight into the interactions occurring in these complexes.

Summary: The study revealed a case of polymerization isomerism in cluster chemistry when [Co(CO)(4)](-) reacts with M(I) compounds (M = Cu, Ag, Au), resulting in the formation of trinuclear clusters with unique molecular structures. This phenomenon was further explored both experimentally and theoretically, demonstrating that dimerization occurs in the solid state only with Ag species, while Cu and Au species exist as monomers.

Summary: This article describes the formation of superatoms by nanoclusters of Group 11 metals stabilized by dichalcogenido and hydrido ligands, and their relationship with precursor hydrido clusters. It is found that the formation of superatoms involves the loss of hydrides and release of H-2 gas, indicating internal self-redox reactions that require a similar core structure.

Summary: In this study, coinage metal-ether complexes supported by N-heterocyclic carbenes were synthesized, characterized, and computationally analyzed. The complexes showed a notable ability to bind Et2O and H2O, which is attributed to a sigma-hole bonding mechanism with an almost linear disposition. This enhanced ability surpasses that of non-covalent interactions involving main group species.

Summary: CCSD(T) calculations on H2S horizontal ellipsis X (X = N-2, CO, CS and SiO) series provide reliable structures, energy properties, and covalency of hydrogen bonds (HB). Symmetry adapted perturbation theory analysis demonstrates the dominant role of electrostatic interactions for the relatively stronger HBs, while the dispersion demonstrates the attraction of the very weak HB of H2S horizontal ellipsis N-2. The covalent character is analyzed by AIM theory and topological analysis on electron density functions, indicating the very weak strength of HBs with a non-covalent character.
