A series of binuclear lanthanide(III) complexes: Crystallography, antimicrobial activity and thermochemistry properties studies

Core–shell Ag@SiO2 nanoparticles of different silica shell thicknesses: Preparation and their effects on photoluminescence of lanthanide complexes

“…The absorption peak of benzoate at 224 nm shifts to 219-223 nm in the complexes, which indicates that the lanthanide ions coordinate with benzoate [36]. The absorption peak of 1,10-phenanthroline at 263 nm shifts to 264 nm in the complexes, which indicates that the lanthanide ions coordinate with 1,10-phenanthroline [34]. It can also be seen that the absorption peak of 2,2 0 -bipyridine at 287 nm shifts to 288 nm in the complexes, which indicates that 2,2 0 -bipyridine is involved in the coordination [35].…”

“…And the d (C-H) absorption peaks shift from 854 and 741 cm À1 to the region of 844-846 and 727-728 cm À1 . This indicates that the coordinate bonds have formed between the lanthanide ions and 1,10-phenanthroline[34]. In the IR spectrum of 2,2 0 -bipyridine, the n C¼N stretching vibration peak appears around 1579 cm À1 and the d (C-H) out-of-plane bending vibration peak appears around 757 cm À1 .…”

Synthesis, thermal study and some properties of Gd(III), Tb(III), Dy(III) and Er(III) complexes with 4,4′-bipyridine and dibromoacetates

“…These spectra are very similar. For all compounds, the m as (COO) [22][23][24]. For Er(III) compound, probably bridging non-completely equivalent bonds between Er(III) and carboxylate groups exists [25].…”

Lanthanide Complexes with 2,3-Dimethoxybenzoic Acid and Terpyridine: Crystal Structures, Thermal Properties, and Antibacterial Activities

“…The search of lanthanide aromatic carboxylic acid complexes have aroused great interest for their various and fascinating structures, which exhibit potential applications for extraction and separation, drug delivery, luminescent probes, and so on . These complexes combine central metallic units with organic N‐donor, which may enhance conjugate function, rigidity and stability, and reinforce the luminescent properties of the complexes .…”
