👋 Our new paper in @natchem.nature.com shows a molecular ferrimagnet that produces almost no external magnetic field and persists well above room temperature.🧲🌡️ Cr(pyrazine)₃ is a simple metal-organic framework with magnetic interactions comparable to the strongest known in inorganic materials. 🔗👇

🎉 Now out in JACS! @jacs.acspublications.org Led by the Reinholdt group, we report a high-spin mixed-valent V=P=V complex with unusual electronic structure and bonding. Check it out here 👇 🔗https://pubs.acs.org/doi/10.1021/jacs.5c20647

💫 Quantum Phenomena and Emergent Properties in MOFs ⚛️ is a symposium at the International Conference on Coordination Chemistry in 🇩🇰 this summer, organized by myself and Lars Öhrström. 🏃‍➡️ We welcome submissions for oral contributions by Sunday, March 1 ⏰ iccc2026.com #MOFs #coordinationchemistry

Just out in @jacs.acspublications.org: "Interplay of Redox Non-Innocence and Symmetry Breaking in a 4d Coordination Framework" 🧪We’ve made Mo(pyz)₂I₂, the 4d cousin of the Cr(pyz)₂X₂ family—with redox-active ligands, symmetry breaking, semiconducting transport, and strong magnetic interactions. 🔗👇

🎓 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.
