Electronic synergy between metal ions and organic linkers is a key to engineering molecule-based materials with high electrical conductivity and, ultimately, metallicity. To enhance in metal-organic solids, chemists aim bring the electrochemical potentials of constituent bridging ligands closer quest obtain metal-d ligand-π admixed frontier bands. Herein, we demonstrate critical role ion tuning electronic ground state such materials. While VCl2(pyrazine)2 an insulator, TiCl2(pyrazine)2...
Bespoke van der Waals (vdW) crystals provide control over the generation, confinement, and transport of charge, spin, light, heat within between atomically precise two-dimensional (2D) layers. We report a novel functionality in vdW by actuating valence changes metal-organic antiferromagnet through molecular alloying. The quadratic net materials Cr(pyz)2Br2 Cr(pyz)2I2 (pyz = pyrazine) are aliovalent, with different Cr(III) Cr(II) oxidation states due to disparate crystal field potentials...
Group 6 metal hexacarbonyl complexes are employed as building blocks for pyrazine-pillared metal–organic frameworks with zero-valent centres.

β-Diketonates, such as acetylacetonate, are amongst the most common bidentate ligands towards elements across entire periodic table and considered wholly redox-inactive in their complexes. Herein we show that complexation of 1,1,1,5,5,5-hexafluoroacetylacetonate (hfac- ) to CrII spontaneously affords CrIII a reduced β-diketonate radical ligand scaffold, evidenced by crystallographic analysis, magnetic measurements, optical spectroscopy, reactivity studies, DFT calculations. The possibility...
Tailoring the chemical surroundings of chromium(<sc>ii</sc>) allows reversible electron-transfer to ubiquitous, purportedly redox-inactive acetylacetonate.
Abstract Tessellation of self-assembling molecular building blocks is a promising strategy to design metal-organic materials exhibiting geometrical frustration and ensuing frustrated physical properties. Appearing in two-dimensional quasiperiodic phases, tilings consisting five-vertex nodes are regarded as approximants for quasicrystals. Unfortunately, these structural motifs exceedingly rare due the complications acquiring five-fold coordination confined plane. Lanthanide ions display...
Layered double hydroxides (LDHs) occur naturally and are synthesized for catalysis, drug delivery, contaminant remediation. They consist of Me(II)–Me(III) hydroxide sheets separated by hydrated interlayers weakly held anions. Often, LDHs nanocrystalline, sheet stacking arrangement can be disordered, which influences the reactivity complicates structural characterization. We have used pair distribution function (PDF) analysis to provide detailed information about local medium range order (≤9...
General interest in the deployment of molten salt reactors (MSRs) is growing, while available data on uranium-containing fuel candidates remains scarce. Thermophysical are one key parameters for reactor design and understanding operability. Hence, filling gap missing crucial to allow advancement MSRs. This study provides novel two eutectic compositions within NaF-KF-UF4 ternary system which serve as potential Experimental measurements include their melting point, density, fusion enthalpy,...
