Summary: Dinuclear complexes [M(H3L1,2,4)](2) (M = Dy, Dy-2; M = Ho, Ho-2) were isolated from a heptadentate aminophenol ligand, with the dysprosium complex showing the largest energy barrier to date for this type of double phenoxide-bridged complexes. The holmium complex exhibits frequency-dependence but does not display field-induced SMM behavior above 2 K. Ab initio calculations were used to understand the magnetic properties of the complexes, which supported the experimental magnetic results.

Summary: Two polymorphic Fe-II coordination polymers were obtained using a redox-active tetrathiafulvalene (TTF) functionalized ligand and a highly luminescent connector. These coordination polymers retained the redox activity of the TTF unit, with complex 1 showing gradual spin transition behavior and a correlation between fluorescence intensity of TPPE and spin crossover transition.

Summary: As an aprotic O-donor ligand, 4,4'-bipyridine N,N'-dioxide (DPO) has been used in the preparation of various uranyl coordination compounds under different reaction conditions. The competition and cooperation between DPO and other O-donors in the formation of these compounds have been discussed. In addition, physicochemical characterization of UDPO-7 and U-DPO-10, including infrared spectroscopy, thermogravimetric analysis, and luminescence properties, has been provided.

Summary: The Ln(III)-tripodal Schiff base complex (TbLtrpn)-L-III was prepared, with the three arms of the ligand extended by one methylene compared to (TbLtren)-L-III. The enhanced TbIII-centered luminescence in (TbLtrpn)-L-III was attributed to the diminished symmetry of the seven-coordination environment of the Tb-III center, leading to an increased radiative transition rate. This provides a new insight for improving the luminescence properties of lanthanide metal complexes.

Summary: Two 4f and 3d-4f complexes were constructed from a Schiff base ligand and showed different structures with open 3D channel structures formed in the solid state. Excited by ligand-centered absorption bands, the complexes exhibited typical NIR emission of Yb3+ and Nd3+, with complex 2 also showing lanthanide luminescent response towards anions such as CN- and OAc- at ppm level.

Summary: A bidentate Schiff base and its 1,3,4-oxadiazole complexes were synthesized and characterized, showing strong electrophilic or nucleophilic tendencies in polar organic reactions, and enhanced antibacterial activity. The metal ions formed stable complexes with the Schiff base, exhibiting higher affinity towards chromium ions and improved biological activity, suggesting potential applications in antimicrobial therapy.
