4-[4-(Diethyl-amino)-phen-yl]-N-methyl-3-nitro-4H-chromen-2-amine.

ABSTRACT: In the title compound, C(20)H(23)N(3)O(3), the dihydro-pyran ring adopts half-chair conformation. The chromene system makes a dihedral angle of 87.35?(5)° with the adjacent benzene ring. An intra-molecular N-H?O hydrogen bond generates an S(6) motif, which stabilizes the mol-ecular conformation. In the crystal, weak inter-molecular C-H?O hydrogen bonds contribute to the stabilization of the packing.

(4S*)-2-Methyl-amino-3-nitro-4-(4-nitro-phen-yl)-5,6,7,8-tetra-hydro-4H-chromen-5-one.

Project description:The title compound, C16H15N3O6, is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The six-membered carbocyclic ring adopts an envelope conformation with the central CH2 C atom as the flap. The amine N atom deviates from the mean plane of the pyran ring by 0.1365?(15)?Å. The nitro-phenyl ring is almost orthogonal to the pyran ring and the mean plane of the six-membered carbocyclic ring, the dihedral angle between their mean planes being 88.30?(7) and 87.61?(8)°, respectively. The mol-ecular structure is stabilized by an intra-molecular N-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming infinite bands lying parallel to (-110) and composed of alternate R 2 (2)(24) and R 2 (4)(12) graph-set ring motifs. The crystal structure is further stabilized by C-H?? inter-actions, forming a three-dimensional structure.

Project description:In the title compound, C16H15BrN2O4, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the disordered methyl-ene C atom as the flap. The pyran ring is almost orthogonal to the chloro-phenyl ring, making a dihedral angle of 87.11?(12)°. The amine-group N atom deviates significantly from the pyran ring [0.238?(3)?Å]. The mol-ecular structure is stabilized by an intra-molecular N-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, which generate C(8) chains running parallel to the b axis. The chains are linked by C-H?? inter-actions. The methyl-ene-group C atom of the chromene system that is disordered, along with its attached H atoms and the H atoms on the two adjacent C atoms, has an occupancy ratio of 0.791?(7):0.209?(7).

6-Ethyl-N-methyl-3-nitro-4-nitro-methyl-4H-chromen-2-amine.

Project description:In the title compound, C(13)H(15)N(3)O(5), the O and N atoms of the nitro-methyl group and the methyl C atom of the ethyl group are disordered over two sets of sites with refined occupancies of 0.629?(7):0.371?(7) and 0.533?(8):0.467?(8), respectively. The dihydro-pyran ring has an extremely flattened conformation. An intra-molecular N-H?O hydrogen bond occurs. In the crystal, pairs of N-H?O hydrogen bonds link mol-ecules, forming inversion dimers.

6,8-Dichloro-N-methyl-3-nitro-4-nitro-methyl-4H-chromen-2-amine.

Project description:In the title compound, C(11)H(9)Cl(2)N(3)O(5), the dihydro-pyran ring adopts a near-half-chair conformation. The benzene ring makes a torsion angle of 5.02 (5)° with the dihydro-pyran ring. Adjacent mol-ecules are inter-linked through inter-molecular C-H⋯O, N-H⋯O and C-Cl⋯π [3.4743 (9) Å] inter-actions. The inter-molecular N-H⋯O hydrogen bond generates an R(2) (2)(12) motif, which is observed to contribute to the crystal packing stability. Moreover, the mol-ecular structure displays an S(6) motif formed by intra-molecular N-H⋯O hydrogen bonding.

Crystal structure of 2-methyl-amino-4-(6-methyl-4-oxo-4H-chromen-3-yl)-3-nitro-pyrano[3,2-c]chromen-5(4H)-one with an unknown solvate.

Project description:In the title compound, C23H16N2O7, the mean planes of the two chromene units (r.m.s. deviations = 0.031 and 0.064 Å) are almost normal to one another with a dihedral angle of 85.59 (6)°. The central six-membered pyran ring has a distorted envelope conformation, with the methine C atom at the flap. There is an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(12) ring motif. The dimers are linked by pairs of C-H⋯O hydrogen bonds, enclosing R 2 (2)(6) ring motifs, forming zigzag chains along [001]. The chains are linked by a second pair of C-H⋯O hydrogen bonds, forming slabs parallel to (110). Within the slabs there are C-H⋯π inter-actions present. A region of disordered electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as plausible solvent mol-ecule(s). The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

Crystal structure of 4-(4-meth-oxy-phen-yl)-7,7-dimethyl-2-methyl-amino-3-nitro-7,8-di-hydro-4H-chromen-5(6H)-one.

Project description:In the title compound, C19H22N2O5, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the dimethyl-substituted C atom as the flap. The pyran ring has a flat-boat conformation. The meth-oxy-phenyl ring is orthogonal to the mean plane of the chromene moiety, with a dihedral angle of 89.97?(8)°. The amine N atom deviates from the chromene mean plane by 0.1897?(16)?Å. The methyl-amine and the nitro group are involved in an intra-molecular N-H?O hydrogen bond which generates an S(6) ring motif. They are slightly twisted out of the plane of the chromene moiety with torsion angles of C-N-C-O(pyran) = 2.2?(3)° and O(nitro)-N-C-C = -5.6?(2)°. In the crystal, there are only C-H?? inter-actions present, forming inversion-related dimers.

4-(4-Bromo-phen-yl)-7,7-dimethyl-2-methyl-amino-3-nitro-7,8-di-hydro-4H-chromen-5(6H)-one including an unknown solvate.

Project description:In the title compound, C18H19BrN2O4, the chromene unit is not quite planar (r.m.s. deviation = 0.199?Å), with the methyl C atoms lying 0.027?(4) and 1.929?(4)?Å from the mean plane of the chromene unit. The six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation, with the dimethyl-substituted C atom as the flap. The methyl-amine and nitro groups are slightly twisted from the chromene moiety, with C-N-C-O and O-N-C-C torsion angles of 2.7?(4) and -0.4?(4)°, respectively. The dihedral angle between the mean plane of the chromene unit and the benzene ring is 85.61?(13)°. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif, which stabilizes the mol-ecular conformation. In the crystal, mol-ecules are linked via N-H?O hydrogen bonds, forming hexa-gonal rings lying parallel to the ab plane. A region of disordered electron density, most probably disordered ethanol solvent mol-ecules, occupying voids of ca 432?Å(3) for an electron count of 158, was treated using the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. Their formula mass and unit-cell characteristics were not taken into account during refinement.

4-[(Dimethyl-amino)methyl-idene]-2-(4-nitro-phen-yl)-1,3-oxazol-5(4H)-one.

Project description:The title mol-ecule, C(12)H(11)N(3)O(4), is essentially planar, the r.m.s. deviation for all non-H atoms being 0.068?Å. An intra-molecular C-H?N hydrogen bond occurs. The crystal packing is dominated by ?-? inter-actions [shortest centroid-centroid distance = 3.6312?(16)?Å], which lead to supra-molecular chains that are linked into a three-dimensional network via C-H?O contacts. The crystal was found to be a non-merohedral twin (twin law -1 0 0/0 -1 0/ 0.784 0 1), the fractional contribution of the minor component being approx-imately 22%.
