🎓 Early Announcement: The 10th European Conference on Molecular Magnetism (ECMM 2026) will be held in Copenhagen, Denmark — Aug 17–20, 2026. Plenary & keynote talks + great opportunities for early-career researchers. 🌐 www.conferencemanager.dk/ecmm #ECMMCopenhagen #MolecularMagnetism #Copenhagen

🧪 Simplicity engineered for magnetism 🧲 📢 Preprint: Cr(pyrazine)₃ - maybe the simplest MOF with potential voids known. Built from Cr(III) + radical pyrazine linkers, this perovskite analogue shows magnetic interactions rivaling the strongest known in inorganic materials, stabilizing order above RT.

📣 New preprint: "4f-intermediate valence in an ytterbium–bipyridine coordination solid" chemrxiv.org/engage/chemr... We report exp. evidence for a multiconfigurational electronic ground state in a ytterbocene-based 1D polymer - the first example of intermediate valence in a coordination solid. ⚛️

🎉 Just out in Nature Comm @natcomms.nature.com "Unleashing phosphorus mononitride" 👉 www.nature.com/articles/s41... Spearheaded by the Reinholdt group (Lund), we find that the elusive P≡N molecule finds new life in an Os complex and unlocks unique [NPS₂]²⁻, [NPCl]⁻, and aromatic [PN₄]⁻ species.
