👋New preprint: "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 very strong magnetic interactions.

🧪 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.

Honored to receive the 2025 Bjerrum Gold Medal 🏅 for "outstanding contributions to inorganic and coordination chemistry", awarded at the Danish Chemical Society Annual Meeting.
