Identification of new N–Sb topologies: understanding the sequential dehydrochloride coupling of primary amines and trichloropnictines

Subtle steric strain imposed by 2,6-dimethylphenyl substituents on N–Sb frameworks has enabled identification of the first acyclic dipnictadiazane and the first six-membered cyclotristibatriazane providing insight into the dehydrohalide coupling reaction of amines with halopnictines.
