Summary: This study synthesized and characterized twelve Re(i) tricarbonyl diimine complexes with thiotetrazolato ligands. The tetrazolato ligand can bind to the Re(i) center through either the S atom or the N atom, with most complexes being bound to the N atom. In solution, the complexes exist as an equilibrating mixture of linkage isomers. The complexes exhibit photoluminescent properties, with emission wavelengths dependent on the nature of the diimine ligand.

Summary: In this study, a series of mono- and binuclear triazolate complexes were synthesized through catalyst-free [3+2] cycloaddition coupling, with the isomerization process from the kinetically formed N(1) bound triazolate isomer to the N(2) analogue successfully evidenced. The solvatochromism properties of these complexes were assessed using UV/Vis spectroscopy and time dependent density functional theory calculations. Additionally, the potential antimicrobial activity of the free ligands and their tricarbonyl triazolato Re(i) complexes against various bacterial and fungal pathogens was preliminarily evaluated.

Summary: Organelle-targeted photodynamic therapy (PDT) using a tricarbonyl Re(I) complex (Re-BDP) was shown to effectively kill cancer cells by generating toxic reactive oxygen species (ROS) in the endoplasmic reticulum (ER). Re-BDP exhibited strong absorbance and high singlet oxygen quantum yield, and preferentially accumulated in the ER. Upon visible light irradiation, Re-BDP showed high phototoxicity and induced caspase-dependent apoptosis accompanied by mitochondrial dysfunction. This study highlights the potential of developing efficient organelle-targeted phototherapeutic agents by conjugating metal complexes and organic chromophores.

Summary: This study investigates the impact of a thione/selone ligand on the cell toxicity and light activity of diimine Re(CO)3+ complexes. Six rhenium(I) complexes were prepared and characterized using multiple techniques. These complexes showed significant cytotoxicity against the human breast cancer cell line MDA-MB-231. The most toxic complex in the series had a similar inhibitory concentration as the corresponding aqua complex.

Summary: Rhodium complexes of biphenylcorrole were synthesized and their molecular structures were confirmed by single-crystal X-ray analysis. The dicarbacorrole moiety effectively stabilizes rhodium metal ion in two different oxidation states. It was observed that the Rh(I) complex exhibited square-planar geometry, while the organo-Rh(III) complex formed an octahedral coordination. Additionally, density functional theory calculations supported the experimental findings.

Summary: The study presents the mechanoresponsive luminescence (MRL) activity of two Re-I complexes with solid-state luminescence enhancement (SLE). Quantum chemical calculations reveal the existence of two low-lying triplet excited states, affecting the emission properties with intraligand and metal-to-ligand charge-transfer character. The transition between these states is promoted by rotation around specific bonds, influencing the emitted wavelength of photoluminescence.
