Description
Rhett T Bryant and co-authors made twin-iron complexes in 2026 that hold a nitrogen pair between two iron atoms. Heat then tore all four bonds of a silicon gas at once. Nitrogen-bridged twin-metal hosts are rare for iron in its lowest charge state. The team formed them by stripping electrons from iron chloride starters with one or two reduction steps.
Full checks with sound-based, crystal, and iron-probe tools confirmed the new hosts and their calm spin state. Warming them with silane gas split each of its four hydrogen bonds, which left a silicon atom pinned between the two irons, each iron also holding two hydrogens. The iron-to-silicon bonds rank as the shortest yet seen, and the three atoms sit near a straight line. The work extends a trick first shown with cobalt to iron.
