A team of researchers from University Erlangen-Nürnberg, Nanjing Tech University and Philipps-Universität Marburg has found that it is possible to use calcium(I) with β-diketiminate as a ligand and potassium as a terminal reductant for dinitrogen reduction. In their paper published in the journal Science, the group describes how they tried to make a calcium(I) complex in their lab using bulky ligands as a means to stabilize the ion and how that led them to a new discovery about calcium.
