Series of Microporous Redox‐Active Pillared Metal–Organic Frameworks Based On Alloxazine Ligands

ChemistryOpen, Volume 14, Issue 12, December 2025.
Two series of robust pillared metal–organic frameworks using a redoactive ligand based on alloxazine and transition metals have been evidenced by XRD. The compounds have high decomposition temperatures, and their sorption properties are measured, revealing relatively low surface areas and a moderate uptake of CO2 and C2H4 at high pressures.

Filling Voids: Cubic Carbodiimide Nitride Nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 17, November 25, 2025.
The crystal structures of (Ba6Nx)2[MN4][CN2]6 (left) and “ideal” 2 × 2 × 2 Perovskite (right) show similar linkage patterns despite differently shaped coordination polyhedra. Cubic carbodiimide nitride nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W are synthesized by various high‐temperature reactions and their respective crystal

Two Polymorphs of the Magnetic Catena‐Orthoperiodato‐Cuprate(II) K3[CuIO6]·4H2O from Ultra‐Alkaline Media

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 16, November 14, 2025.
The ultra‐alkaline condition of a hydroflux facilitate the synthesis of a new periodato cuprate(II). Fully deprotonated orthoperiodate octahedra are connected into chains by copper(II) cations. The two modifications differ in the constitution of these chains, which influences the magnetism of the compounds.
