1,2,4-Diazaphospholide Complexes of Tin(II): From Nitride Stannylene to Stannylenated Ammonium Ions 

An unusual nitride tetrastannylene and a stannylenated ammonium ion stabilized by a samarium tetradiazaphospholido counterion are the first examples of a tris(organostannylenyl)amine derivative and a divalent tin coordinate onium ion that incorporates 1,2,4-diazaphospholide ligand.
