Crystal structure of 4-aminopyridinium 5-(5-chloro-2,4-dinitrophenyl)-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-olate hemihydrate
The title mol-ecular salt, C5H7N2 (+)·C12H8ClN4O7 (-)·0.5H2O, crystallizes as a hemihydrate. The two rings in the barbiturate anion are not coplanar but make a dihedral angle of 43.17 (16)°. The two nitro groups deviate from the ring to which they are attached; the nitro group ortho with respect to the ring junction is more deviated [39.3 (4)°] than that in the para position [4.2 (5)°], probabl...

In the title mol-ecular salt, C(5)H(7)N(2) (+)·C(12)H(8)ClN(4)O(7) (-), the dihedral angle between the aromatic rings of the anion is 51.88 (6)°. One of the nitro groups is disordered over two orientations in a 0.710 (6):0.290 (6) ratio. In the crystal, the cations and anions are linked by N-H⋯O hydrogen bonds, generating infinite ribbons extending along [100] which incorporate R(4) (4)(22) rin...

IN THE TITLE BARBITURATE SALT (TRIVIAL NAME: trimethyl-ammonium 2,4,6-trinitro-phenyl-barbiturate), C(3)H(10)N(+)·C(10)H(4)N(5)O(9) (-), the asymmetric unit contains two sets of anion-cation moieties. The dihedral angle between the rings in the anions are 44.0 (3) and 45.7 (3)°. Adjacent anions are connected into ribbons along [100] through R(2) (2)(8) ring motifs formed by N-H⋯O hydrogen bonds...
متن کاملN,N-Diethylanilinium 2,4-dioxo-5-(2,4,6-trinitrophenyl)-1,2,3,4-tetrahydropyrimidin-6-olate
In the crystal structure of the title mol-ecular salt, C(10)H(16)N(+)·C(10)H(4)N(5)O(9) (-), the components are linked through a N-H⋯O hydrogen bonds. R(2) (2)(8) ring motifs are formed between inversion-related barbiturate residues. Two intra-moleculer N-H⋯O hydrogen bonds are observed in the anion. The dihedral angle between 2,4,6-trinitro-phenyl and barbiturate rings is 53.6 (2)°. The N,N-di...
متن کاملSynthesis of a new class of carbon–bonded anionic sigma complexes with 1,3-dimethyl-2,6-dioxo-5-(2,4,6-trinitrophenyl)-1,2,3,6-tetrahydropyrimidin-4-olate moiety as insensitive high energy density materials –– implications from impact sensitivity and thermal testings
BACKGROUND Poly nitro aromatic compounds are high energy density materials. Carbon-bonded anionic sigma complexes derived from them have remarkable thermal stability. At present there is a strong requirement for thermally stable insensitive high energy density materials (IHEDMs) in the energetic field which necessitates the present investigation. RESULTS Three new carbon-bonded anionic sigma ...
