262. The crystal structure of s-bisnitroaminoethane (ethylene dinitroamine)

The crystal structure of nitroguanidine

“…Few nitramines have been subjected to X-ray structure analysis. Llewellyn & Whitmore (1948) made a complete analysis of the structure of ethylenedinitramine, and the structure of the disodium salt of this compound was reported by Allentorf & Wright (1953). * Present address: Gates and Crellin Laboratories of Chemistry, California Institute of Technology, Pasadena 4, Califor-Ilia, U.S.A. Costain & Cox (1947) have briefly described the partial analysis of dimethylnitramine.…”

Energetic propane-1,3-diaminium and butane-1,4-diaminium salts of N,N′-dinitroethylenediazanide: syntheses, crystal structures and thermal properties

“…Ethylenedinitramine (EDNA; systematic name: N,N 0 -dinitroethylenediamine) is a secondary explosive that was initially developed at the Picatinny Arsenal in 1935 (Hale, 1935) as a potential substitute for the then most commonly used explosive RDX. Its complete crystallographic analyses were reported in 1948 (Llewellyn & Whitmore, 1948). However, its crystal structure was not reported in the Cambridge Structural Database (CSD; Groom et al, 2016) until 1968Turley, 1968), and that is the only entry to date for EDNA in the CSD.…”

Structure of N,4-dinitroaniline and its complex with sulfolane at 85 K; on the proton donor–acceptor affinity of the primary nitramine (HNNO2) group

“…In the structure of N,N H -dinitroethylenediamine, the dipole±dipole interaction is the predominant crystal binding force. One short intermolecular distance (NÐHÁ Á ÁO 3.007 A Ê ) may be considered as a weak hydrogen bond, but its in¯uence on the crystal packing is negligible (Llewellyn & Whitmore, 1948;Turley, 1968). In the primary nitramines of the pyridine series, containing an additional basic centre in the aza-aromatic ring, the proton transfer is almost complete.…”
