Arylacylhydrazones of 2,3-dihydroxybenzaldehyde are appropriate ligands for the preparation of heterodinuclear triple-stranded helicates involving high coordinated lanthanide(III) ions. In the present study, three different kinds of substituents are introduced at the ligands in order to modify the organic periphery of the coordination compounds: (1) alkoxy groups are attached to the terminal phenyl groups, (2) NH protons of the hydrazones are substituted by phenyl moieties and (3) amino acid bearing units are attached to the terminus of the ligand. The new ligands nicely form the desired triple-stranded gallium(III)-lanthanum(III) complexes [(5a-c,7,12,15)(3)GaLa] of which the highly phenylated derivative was crystallized and studied by X-ray diffraction.

This work presents the synthesis and characterization of three isomorphous lanthanide-based metal-organic frameworks (Ln-MOFs) (Ln=Eu (1), Tb (2), and Sm (3)) supported by a pyridine-2,6-dicarboxamide-based linker offering appended arylcarboxylate groups. Single crystal X-ray diffraction studies highlight that these Ln-MOFs present three-dimensional porous architectures offering large cavities decorated with hydrogen bonding (H-bonding) groups. These Ln-MOFs display noteworthy luminescent characteristics.

We present the design and synthesis of two novel isostructural metalloring organic frameworks (MROFs) {[(MeNH)(HO)NaX(μ-OH)(HO)(SIP)]·sol} (FUT-2-X, X = Eu and Sm), which are composed of the sulfonate-carboxylate ligand 5-sulfoisophthalic acid monosodium salt (NaHSIP) and an unprecedented lanthanide-sodium metalloring [XNa(HO)(SIP), X = Eu and Sm]. The two MROFs possess channel walls decorated with uncoordinated sulfonic acid groups and filled with abundant guest molecules residing within the framework, which support the proton conductivity of the materials by expanding the intermolecular hydrogen bonding network. FUT-2-Eu exhibits exceptional proton conductivity over a wide temperature range, achieving conductivity from 1.

Lanthanide-containing clusters are synthetically challenging and with significant chemical and materials applications. Herein, two isostructural heterometallic clusters of the formula (NO)@[LnNi(OH)(IDA)(CHCOO)(NO)(HO)]Cl⋅xHO⋅yCHOH (IDA=iminodiacetate; Ln=Gd 1, x=110, y=0; Ln=Eu 2, x=95, y=40) were obtained via co-hydrolysis of Ln (Gd or Eu) and Ni in the presence of iminodiacetate (IDA). Crystallographic studies show that each features a truncated tetrahedral core of LnNi within which a void of 1.

Liver fibrosis is a pathological repair response that occurs after sustained liver damage, and prompt intervention is necessary to prevent liver fibrosis from developing into a potentially life-threatening condition. In long-term liver injury, damaged hepatocytes produce excessive amounts of reactive oxygen species (ROS), which activate hepatic stellate cells (HSCs). This activation leads to excessive accumulation of extracellular matrix proteins in liver tissue.
