The [NH2C(I)NH2]3SnI5 structure has recently been reported in the monoclinic space group P21/c and consists of highly distorted SnI6 octahedra which share opposite corners to form extended one-dimensional chains separated by iodoformamidinium cations. The new mixed-cation compound adopts a very...

(NHOs) have gone from the topic of a few scattered (but important) reports in the early 1990s to very recently being a ligand/reagent of choice in the far-reaching research fields of organocatalysis, olefin and heterocycle polymerization, and low oxidation state main group element chemistry. NH...
