Summary: Six Dy(III) single-ion magnets with different magnetic properties were synthesized, with complex 6 showing the best performance and its magnetic hysteresis loop remaining open at a low temperature of 21 K. Crystal structures revealed a switching of local symmetry as a main factor for magnetic property distinctions, along with the impact of OMe-substituted groups. These results highlight the importance of considering positional isomerism when designing ligands for Dy-SIMs to avoid overlooking potential factors affecting magnetic performance.

Summary: A series of five novel Mn-salen-based compounds (1a-1c, 2a, 2b) were synthesized through the reaction between precursor chloride complexes and potassium silver/gold dicyanide. The compounds were structurally and magnetically characterized. The findings revealed that the Mn(III) central atoms exhibited axial magnetic anisotropy, and weak magnetic exchange was observed in compounds with a special supramolecular topology involving O-H···O hydrogen-bonded dimers.

Summary: This paper presents the synthesis of two coordinatively unsaturated Co-salen complexes, which exhibit high activity and CO selectivity for visible-light-driven CO2 reduction. The photocatalytic performance of catalyst 2 is superior to that of catalyst 1 due to the lower reduction potential and energy barrier of its catalytic CoII center. Control experiments and density functional theory calculations provide strong evidence to support the photocatalytic reduction of CO2 to CO by catalyst 2.

Summary: Under the action of a catalyst, the photoinduced reduction of CO2 to chemicals and fuels is a green and environment-friendly approach to reduce atmospheric CO2 emissions. Researchers have been exploring efficient photoinduced CO2 reduction systems, especially non-noble metal complexes. A new binuclear cobalt complex, Co2L1, was reported, which showed significantly higher catalytic activity for visible-light-driven CO2 conversion to CO compared to Co2L2. Co2L1 exhibited excellent CO selectivity of 98% and a high TONCO of 5920, thanks to the electron-donating effect of the methoxy group (-OCH3) in Co2L1.
