In the centrosymmetric binuclear title complex, [Yb(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Yb(III) ions are linked by two 2-phen-oxy-propionate (L) groups in a bidentate bridging mode. Each Yb(III) ion is eight-coordinated by two O atoms from two bridging L ligands, four O atoms from two chelating L groups and two N atoms from one chelating phen mol-ecule in a distorted YbN(2)O(6) dodeca-hedral geometry.

The title compound, [Zn(CHClNO)Cl], is a dinuclear zinc(II) complex with three chlorido ligands and one penta-dentate ligand containing quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine groups. One of the two Zn atom adopts a tetra-hedral geometry and coordinates two chlorido ligands with chelate coord-ination of the N and O atoms of the quinolin-8-olato group in the ligand. The other Zn atom adopts a distorted trigonal-bipyramidal geometry, and coordinates one chlorido-O atom of the quinolin-8-olato group and three N atoms of the bis-(pyridin-2-ylmeth-yl)amine unit.

Nanofiltration (NF) is crucial for advancing water purification and wastewater reuse technologies. Incorporating biocidal nanoparticles (NPs) such as AgNPs and CuNPs is promising for developing antibacterial and antibiofouling NF membranes, while their application is limited by NPs aggregation, high cost, and severe ion release. In this study, we developed novel NF membranes by integrating bimetallic AgCu nanoalloys via an in-situ reduction and coordination method facilitated by a polydopamine/polyethyleneimine (PDA/PEI) intermediate layer.

Single-crystal structures of four alditol complexes are presented. In LuCl/galactitol and ScCl/-inositol complexes, μ-bridge-relevant deprotonations were observed. The polarization from two rare earth ions in the μ-bridge activates the chemically inert OH and promotes deprotonation.

If we aim to develop efficient synthetic models of protein receptors and enzymes, we must understand the relationships of intra- and intermolecular interactions between hosts and guests and how they mutually influence their conformational energy landscape so as to adapt to each other to maximize binding energies and enhance substrate selectivities. Here, we introduce a novel design of cofacial (Zn)bisporphyrin cages based on dynamic imine bonding, which is synthetically simple, but at the same time highly robust and versatile, affording receptors composed of only -hybridized C and N atoms. The high structural rigidity of these cages renders them ideal hosts for ditopic molecules that can fit into the cavity and bind to both metal centers, leading to association constants as high as 10 M in chloroform.

Angiotensin-converting enzyme (ACE) inhibitory peptides exhibit antihypertensive effects by inhibiting ACE activity, and the study of the interaction between ACEs and inhibitory peptides is important for exploring new therapeutic strategies. In this study, the ACE-inhibitory peptide isolated from casein hydrolysate with the amino acid sequence Leu-Leu-Tyr (LLY) exhibited high ACE-inhibitory activity and stability, which holds significant implications for biochemistry and pharmaceutical applications. Furthermore, systematic investigations were conducted on the interaction between ACE and LLY through various approaches.
