Summary: This work focuses on the synthesis and physicochemical characterization of four mononuclear copper (I) complexes with pi-conjugated ligands substituted by methyl groups. The geometry of the complexes and the origin of metal-to-ligand charge transfer in a square-planar distortion state were discussed and rationalized using TD-DFT.

Summary: This study investigated the thermochemical and kinetic studies of the formation of iodine (I-2) and 4-(dimethylamino) pyridine (DMAP) complexes in solution using microcalorimetry. The complexation heats as a function of the concentration ratios of DMAP and I-2 showed similar tendencies but different enthalpies, indicating a non-reciprocal phenomenon. By considering the measured and calculated complexation energies, complex forms for the reaction between I-2 and DMAP were proposed. The kinetic mechanisms and theoretical heat flow equations were also proposed for different concentration ratios.

Summary: This study simulated the different catalytic mechanisms of the reaction between CO2 and propargylic alcohol. It was found that metal-assisted catalytic system can enhance the conversion rate and product yield. The PA-activated mechanism was identified as the optimal reaction pathway with intramolecular cyclization as the rate-determining step. The combination of [Ch][Triz] and Ag salts played different roles in promoting the reaction steps.

Summary: A series of Ni(II) trinuclear complexes have been synthesized and characterized, with X-ray crystallographic studies revealing their composition of three face-sharing octahedral Ni(II) metal ions bridged by the phenoxide oxygens of the sala-X ligands. Magnetic studies indicate ferromagnetic coupling between the Ni(II) centers, with substituent groups having minimal impact on the coupling magnitude. DFT calculations support ferromagnetic coupling, with smaller Ni-O-Ni angles leading to slightly larger coupling constants.

Summary: Alloying rare earth (RE) elements is a promising method for enhancing corrosion resistance of Mg-Al alloy. However, high concentrations of RE can exacerbate galvanic corrosion. Density functional theory calculations were conducted to investigate the effects of RE (RE 1/4 Sc, Y, Nd) concentration on galvanic corrosion in Mg-Al alloy. The results demonstrated that low concentrations of RE can alleviate galvanic corrosion, while high concentrations can significantly aggravate it. Additionally, it was found that the effectiveness of mitigating galvanic corrosion followed the order of Sc > Y > Nd. Possible explanations for the experimental observations were provided, and a potential strategy to improve corrosion resistance of Mg-Al alloy was proposed.

Summary: Efficient electrocatalysts for CO2 reduction require a comprehensive understanding of the catalytic architecture and reaction mechanism. Experimental and computational results showed that the Re(I) catalysts with the [Zn(cyclam)](2+) cocatalyst required less energy input for CO2 reduction, but this cocatalyst did not improve activity for the Re(I) electrocatalyst with a strong electron-withdrawing group. This highlights how electronic distribution within the molecular architecture can impact the nucleophilicity of Re-I(bpy-X) electrocatalysts.

Summary: A series of novel 3-N,N-dimethylaminofunctionalized phosphinines were synthesized and characterized. DFT calculations showed their stronger pi-donor and sigma-donor properties compared to C5H5P. Complexes of [(phosphinine)(2)CuBr](2) and mononuclear phosphinine-Au(I)Cl were obtained and characterized. The presence of SiMe3-group and donor-functionality allows for post-synthetic ligand modifications. A rare Cu(I) complex with a Cu4Cl4-core, containing two pairs of differently coordinating phosphinine ligands, was formed with CuCl.SMe2.
