Summary: Neutral homotrinuclear complexes [{Zn-3(L)(2)(mu-OAc)(2)}(2)].5EtOH and [Ni-3(L)(2)(mu-OAc)(2)(MeOH)(2)].2MeOH were synthesized and structurally characterized with X-ray diffraction. The Zn(II) and Ni(II) complexes consist of two (L)(2-) units combined with three metal(II) ions, with bridging mu-OAc- ions neutralizing the charge and stabilizing the trinuclear structure. The Zn(II) complex has mu-OAc- ions on the same side, while the Ni(II) complex has them on different sides. UV-vis absorption analysis confirmed the coordination of the ligand to Zn(II) and Ni(II) atoms, DFT calculations revealed the higher kinetic stability and lower chemical reactivity of the complexes. Fluorescence analysis showed electron transfer to the empty orbitals of Zn(II) and Ni(II) atoms. Hirshfeld surfaces and electrostatic potential analyses provided insights into the crystal structures and sites favorable for hydrogen bonds.

Summary: An experimental and quantum chemical study was conducted on Cu(II) dithiocarbamate complexes, specifically N-butyl-N-phenyldithiocarbamate ([Cu(L-1)(2)]) and N-ethyl-N-ethanoldithiocarbamate ([Cu(L-2)(2)]), to investigate their structures in different media. The study examined the crystal structure, as well as the geometric features in polar and non-polar solvents resembling the biological system environment. Both experimental techniques, including crystallography and spectroscopy, and theoretical calculations using density functional methods were employed to analyze the structure. The results showed that the two copper complexes were semiconductors with indirect bandgaps, and the stability of [Cu(L-2)(2)] was attributed to the oxygen's s-states. Additionally, the study explored the optical properties, such as the absorption spectrum, electronic transitions, and reflectivity, providing important insights into the structural characteristics of these copper complexes when combined with experimental and theoretical findings.

The properties of the complexes were characterized by elemental analyses, single crystal X-ray diffraction, IR spectra, UV-vis spectra, and fluorescence spectra. Complexes 1 and 2 have similar crystal structures but different non-covalent interactions. Complex 1 forms a one-dimensional chain through pi-pi interactions, while complex 2 forms a three-dimensional supramolecular network structure through intermolecular hydrogen bonding interactions. Furthermore, fluorescence experiments showed significant quenching in 1 and 2 compared to H3L. Intermolecular forces were studied using Hirshfeld surface analysis. DFT calculations revealed high chemical reactivity and low kinetic stability in 1 and 2.

Binding with Fe3+ resulted in the quenching of blue fluorescence signal of NQS and a distinct color change from colorless to yellow. On encountering OH-, the deprotonation of phenolic hydroxyl group of NQS led to the enhancement of green fluorescence signal and an instantaneous color change from colorless to bright yellow. Moreover, the addition of H+ could convert the colorimetric and fluoremetric sensing process of OH- by NQS.

Summary: This study describes four heterobimetallic (salen)Al catalysts and demonstrates that cooperative Al/Mg and Al/Zn combinations can significantly enhance catalyst activity, compared to mono-Al analogues. In contrast, Al/Li and Al/Ca combinations were found to inhibit the polymerization rate. Kinetic and computational studies suggest that chloride bridging in close intermetallic proximity enhances initiation and increases available monomer coordination sites in Al/Mg and Al/Zn complexes. Additionally, ab initio molecular dynamics calculations were utilized to investigate catalyst flexibility and reveal that ligand strain and molecular rigidity can enhance the performance of heterometallic catalysts.

Summary: Three tetraphenylarsonium dithiophosphate salts were crystallized in different space groups and stabilized by various non-covalent interactions. The interactions were quantified through thorough Hirshfeld surface analysis, revealing potential nucleophilic and electrophilic attack sites within the molecules. Computational data indicated good agreement between experimental values and optimized structural parameters.
