On the stability and existence of nitro-graphene, nitro-graphane, and nitro-graphene oxide

Kyäni Nitro FXTM and Kyäni Nitro XtremeTM: The Science Behind Kyäni’s Nitric Oxide Precursors

2-Nitro-N-phenyl­benzene­sulfonamide

In the title compound, C(12)H(10)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- fragment is syn to the ortho-nitro group in the sulfonyl-benzene ring. The mol-ecule is twisted at the S-N bond, the C-N-S-C torsion angle being -72.83 (15)°. The dihedral angle between the benzene rings is 59.55 (7)°. The amide H atom and the nitro group O atom form an intra-molecular hydrogen bond, ...

2-Nitro-1,3-dinitro­oxypropane

The title compound, C3H5N3O8, was synthesized by reacting 2-nitro-propane-1,3-diol with acetyl nitrate. The mol-ecule is bisected by a crystallograpic mirror plane. In the crystal, the mol-ecules pack in a ribbon-like fashion along the c axis, with the central nitro groups pointing in the same direction. C-H⋯O contacts apparently provide some additional packing stabilization.

4-Nitro-2-phenoxy­aniline

In the title compound, C(12)H(10)N(2)O(3), the oxygen atom bridging the two aromatic rings is in a synperiplanar (+sp) conformation. The dihedral angle between the aromatic rings is 71.40 (12)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds.

3-Nitro-2-phenyl­chroman

In the title compound, C(15)H(13)NO(3), the dihedral angle between the two aromatic rings is 79.25 (16)°.
