Structure of 2-nitriminoimidazolidine

1-(2,3-Dimethoxybenzyl)-N-nitroimidazolidin-2-imine

“…Bond lengths and angles of the N-nitroimidazolidin-2-imine group are in agreement with those in previous reports (Nordenson, 1981;Ravikumar et al, 2006). The N-nitroimidazolidin-2-imine ring (N1/N2/C10/C11/C12) and benzene rings (C1-C6) make a dihedral angle of 86.98 (2)°.…”

Novel High Energy Intermediate Analogues with Triazasterol‐Related Structures as Inhibitors of Ergosterol Biosynthesis Part I: Synthesis and Antifungal Activity of N‐alkyl‐N′‐(phenethyl‐ and cyclohexenylethyl)guanidines and N2‐Substituted 2‐Imidazolinamines

“…These findings suggest the existence of the nitrimino form 18 iI with exocyclic C-2-N-2 double bond and are not compatibel with tautomer 18 iII containing an unsymmetrically substituted ethylene moiety (Scheme 5). An X-ray analysis accomplished by Nordenson [18] confirmed the 2-nitriminoimidazolidine structure and revealed that intramolecular hydrogen bonds between one oxygen of the nitro group and NH-1 or NH-3 of the imidazolidine are formed in the crystals.The same could be expected for 18 iI in solution, but the two possible forms 18 iI and 18 iIЈ might be in a rapid equilibrium.Thus, only two time average signals for NH and CH 2 protons were observed in the NMR spectra.…”

Categorizing and Understanding Energetic Crystals

“…Energetic N-heterocyclic compounds also possess a high population among energetic molecules, due to a high structural diversity of N-heterocycle. − Some N-heterocyclic compounds, such as the known CL-20, HMX, RDX, and TNAZ, possess nonplanar N-heterocyclic structures. More N-heterocycles are planar each with a conjugated planar molecular skeleton, which thereby increases the molecular stability, such as various azoles, azines, furazans, and their fused or bridged cycles.…”
