Summary: This study reports the formation of an unexpected and unique family of chiral helicates, whose molecular helicity can be controlled by the configuration of bimetallic vertices and exhibits highly enantio- and helix-sense-selective recognition for chiral amino alcohols. The transformation of single-molecule chirality to global supramolecular chirality within well-defined helicates is highly dependent on the superior microenvironments.

Summary: The outcomes of self-assembly reactions are influenced by the interplay of multiple factors. Here, utilizing an acetylene-appended quaterpyridine ligand, it is demonstrated that the size of the metal ion and steric repulsion between the acetylene groups exclusively lead to the formation of [M2L3] helicates instead of a helicate/tetrahedron equilibrium.

Summary: This study reports on the synthesis and reductive elimination reactions of Au(III) methyl complexes. The reactions leading to the formation of C-heteroatom bonds in Au(III) complexes are uncommon and their mechanisms are not well known. The obtained results show that nucleophilic substitution should be considered as a likely reductive elimination pathway in Au(III) alkyl complexes.

Summary: The Debye scattering equation (DSE) is widely used for analyzing total scattering data of nanocrystalline materials. In its modified form (MDSE), contributions from uncorrelated thermal agitation terms and average site-occupancy factors (s.o.f.'s) are included for defective crystalline nanoparticles (NPs). This paper provides a theoretical demonstration of the s.o.f.'s and corrects a glitch in the original MDSE, discussing their physical significance. Three new MDSE expressions are introduced for distinct defective NP ensembles, and the beneficial aspects and shortcomings of introducing s.o.f.'s as refinable parameters are demonstrated through numerical simulations and atomistic modeling.

Summary: The synthesis, structure, and magnetic properties of homometallic hexanuclear lanthanide complexes have been reported. These complexes consist of two trinuclear triangular sub-units linked through phenoxide bridging groups. Complex 1 exhibits a magnetocaloric effect with a maximum value of -Delta S-m = 21.03 J kg(-1) K-1 at T = 3 K and Delta B = 5 T. Complex 3 shows slow relaxation of magnetization even under zero applied field, and a clear maximum in the out-of-phase component of the ac susceptibility is observed under an applied field of 0.2 T.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
