Crystal structures of the dinitrate-bis-(acetylenedicarboxylate) and acetylenedicarboxylate pseudorotaxane complexes of [24-pyrimidinium crown 6]

The reaction of [24-Pyrim C6][NO3]6 ! 8H2O with the monopotassium salt of acetylenedicarboxylic acid yielded single crystals of [24-Pyrim C6][C4O4]2[NO3]2 ! 7 H2O, (1). The compound crystallized in the triclinic space group P1, with a = 9.731(8) Å, b = 10.953(9) Å, c = 14.270 (14) Å, a = 108.06(7)", b = 94.86(7)", c = 99.01(7)", Z = 1, R = 0.0737, R¢ = 0.1024, and 3709 independent reflections. ...

Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Crystal structure of N,N-di­ethyl­benzene-1,4-diaminium dinitrate

In the structure of the title mol-ecular salt, C10H18N2 (2+)·2NO3 (-), the dinitrate salt of 4-(N,N-di-ethyl-amino)-aniline, the two ethyl groups lie almost perpendicular to the plane of the benzene ring [the ring-to-ethyl C-C-N-C torsion angles are -59.5 (2) and 67.5 (3)°]. The aminium groups of the cation form inter-species N-H⋯O hydrogen bonds with the nitro O-atom acceptors of both anions, ...

Crystal structure of 3,3′-biisoxazole-5,5′-bis(methyl­ene) dinitrate (BIDN)

The mol-ecular structure of the title energetic compound, C8H6N4O8, is composed of two planar isoxazole rings and two near planar alkyl-nitrate groups (r.m.s deviation = 0.006 Å). In the crystal, the mol-ecule sits on an inversion center, thus Z' = 0.5. The dihedral angle between the isoxazole ring and the nitrate group is 69.58 (8)°. van der Waals contacts dominate the inter-molecular inter-ac...
