Blue Alkali Dinitrosomethanides:  Synthesis, Structure, and Bonding

Explosive alkali dinitrosomethanides (M[HC(NO)₂]; M = Li, Na, K, Cs) were prepared in a new, simple, high-yielding synthetic procedure, fully characterized, and shown to be stable at ambient temperature. Alkali dinitrosomethanides are of widespread interest to pharmaceutical and materials scientists alike.
