Published: January 2014

In the title compound, [Fe(NCS)2(C8H6N4S2)2] n , the Fe(II) cation is coordinated by two terminal N-bonded thio-cyanate anions and four bridging N:N'-bridging dipyrazin-2-yl di-sulfide ligands in an octa-hedral geometry. The Fe(II) cations are connected via bridging 4,4'-di-pyrazine ligands into chains along the b-axis direction. The asymmetric unit consists of one Fe(II) cation located on position with site symmetry 2/m, one thio-cyanate anion located on a mirror plane and one di-sulfide ligand located on a twofold rotation axis.

"Cofactors" for Natural Products.

Cofactors are non-protein entities necessary for proteins to operate. They provide "functional groups" beyond those of the 20 canonical amino acids and enable proteins to carry out more diverse functions. Such a viewpoint is rarely mentioned, if at all, when it comes to natural products and is the theme of this Concept.

The bistability of multiple physical properties driven by external stimuli in a solid is a desired prerequisite for its application in memory devices with convenient data readout. We present a pathway for thermal bistability detectable in four physical properties: magnetic, light absorption, second-harmonic generation (SHG), and dielectric. We report a novel heterometallic (TBA){[Fe(phIN)][Re(CN)]} ⋅ (phIN) (1) (TBA=tetrabutylammonium cation, phIN=phenyl isonicotinate) cyanido-bridged chain material.

Ion-Mediated Cross-Linking of Hyaluronic Acid into Hydrogels without Chemical Modification.

Biomacromolecules

December 2024

Department of Chemical Engineering & Applied Chemistry, University of Toronto, 200 College Street, Toronto, Ontario M5S 3E5, Canada.

Hyaluronic acid (HA) is a biomedically relevant polymer widely explored as a component of hydrogels. The prevailing approaches for cross-linking HA into hydrogels require chemically modifying the polymer, which can increase processing steps and complicate biocompatibility. Herein, we demonstrate an alternative approach to cross-link HA that eliminates the need for chemical modifications by leveraging the interactions between metal cations and the negatively charged, ionizable functional groups on HA.

Heavy-Metal Ions Control on PFAS Adsorption on Goethite in Aquatic Systems.

Environ Sci Technol

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous environmental contaminants that often co-occur with heavy metals. Despite their prevalence, the mobility of PFAS in complex, multicomponent systems, particularly at the molecular scale, remains poorly understood. The vast diversity of PFAS and their low concentrations alongside anthropogenic and natural substances underscore the need for integrating mechanistic insights into the sorption models.
