5H-1-Benzothio-pyrano[2,3-b]pyridin-5-one.

ABSTRACT: Mol-ecules of the title compound, C(12)H(7)NOS, with one half-mol-ecule in the asymmetric unit, are disordered about a crystallographic centre of inversion. Refinement showed that the C=O group is disordered with the S atom and the N atom is disordered over four positions. Adjacent mol-ecules are connected through C-H?O hydrogen bonds and ??? inter-actions (centroid-centroid distances of 3.635 and 3.858?Å).

Mol-ecules of the title compound, C(12)H(7)NOS, with one half-mol-ecule in the asymmetric unit, are disordered about a crystallographic centre of inversion. Refinement showed that the C=O group is disordered with the S atom and the N atom is disordered over four positions. Adjacent mol-ecules are connected through C-H⋯O hydrogen bonds and π⋯π inter-actions (centroid-centroid distances of 3.635 and 3.858 Å). ...[more]

Project description:In the mol-ecule of the title compound, C(12)H(6)N(2)O(3)S, the central heterocyclic ring is oriented at dihedral angles of 3.25?(6) and 2.28?(7)° with respect to the benzene and pyridine rings, respectively. The dihedral angle between the benzene and pyridine rings is 5.53?(7)°. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules into chains.

2,2,10-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-8-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. Due to the -CMe(2)- group, the mol-ecule is not quite planar. The packing is dominated by the strong N-H⋯O hydrogen bonds and some weaker C-H⋯O and C-H⋯π inter-actions. π-π Stacking inter-actions [centroid-centroid separation = 3.806 (2) Å] join neighboring mol-ecules into loosely connected inversion dimers.

2,2-Dimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4(11H)-one.

Project description:The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy-carbazole and 3,3-dimethyl-acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the -CMe(2)- group, the mol-ecule is not quite planar. In the crystal structre, strong N-H⋯O hydrogen bonds and weaker C-H⋯π inter-actions occur, and a slipped π-π stacking inter-action [centroid-centroid separation = 3.8425 (8) Å] is also observed.

2,2,9-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4-(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-7-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. The mol-ecules contain an essentially planar 6-methyl-indole unit. The second aromatic ring is significantly bent away from the plane of this unit, with maximum deviations of 0.171 (1) and 0.185 (1) Å for two of the C atoms. In the crystal structure, there are neither N-H⋯O hydrogen bonds nor π-π stacking between the aromatic sections of neighboring mol-ecules. There is only one weak C-H⋯O hydrogen bond and a number of weak C-H⋯π inter-actions.

3,4-Dimethyl-pyrano[2,3-c]pyrazol-6(2H)-one.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(2)O(2), comprises two independent mol-ecules in both of which, all non-H atoms lie in a common plane (r.m.s. deviation = 0.014 and 0.017?Å). In the crystal, N-H?O hydrogen bonds connect the mol-ecules into zigzag chains running along [10-1]. Weak C-H?O inter-actions connect the chains into an infinite network.

4,8-Dimethyl-pyrano[2,3-a]carbazol-2(11H)-one.

Project description:The mol-ecule of the title compound, C(17)H(13)NO(2), is nearly planar, the r.m.s. deviation for all non-H atoms excluding the two methyl C atoms being 0.089 Å. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds are found in the crystal structure. C-H⋯π inter-actions are also found. The H atoms of the methyl group attached to the benzene ring are disordered equally over two positions.

3,4-Dimethyl-1-phenyl-pyrano[2,3-c]pyrazol-6(1H)-one.

Project description:In the title compound, C(14)H(12)N(2)O(2), the dihedral angle between the phenyl ring and the 3,4-dimethyl-pyrano[2,3-c]pyrazol-6(1H)-one system is 7.28?(6)°. An intra-molecular C-H?O inter-action generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H?O hydrogen bonds, forming C(8) chains. C-H?? and ?-? inter-actions [centroid-centroid separation = 3.6374?(12)?Å] further consolidate the packing.

1-Phenyl-3H-2,3-benzodiazepin-4(5H)-one.

Project description:The seven-membered ring in the title compound, C(15)H(12)N(2)O, adopts a boat-shaped conformation (with the methyl-ene C atom as the prow and the double-bond C=N pair of atoms as the stern). In the crystal, adjacent mol-ecules are linked by an N-H?O hydrogen bond to generate helical chains running along the a axis of the ortho-rhom-bic unit cell.

3,6-Dimethyl-1-phenyl-1H,4H-pyrano[2,3-c]pyrazol-4-one.

Project description:The title compound, C(14)H(12)N(2)O(2), is almost planar with an r.m.s. deviation for all non-H atoms of 0.038?Å. The observed planarity is rationalized in terms of a close intra-molecular C-H?O inter-action. Supra-molecular layers, two mol-ecules thick and with a step topology, are formed in the crystal packing via C-H?O contacts involving the carbonyl O atom, which accepts two such bonds, and ?-? inter-actions between the components of the fused ring system and the phenyl ring of inversion-related mol-ecules [centroid-centroid distances = 3.6819?(13) and 3.6759?(12)?Å].

5-(Pyridin-4-ylmeth-yl)-1H-pyrazolo-[3,4-d]pyrimidin-4(5H)-one.

Project description:In the title compound, C(11)H(9)N(5)O, the pyrazolo-pyrimidin-4-one ring system is almost planar, with a maximum deviation of 0.0546?(13)?Å for the O atom. The crystal packing is stabilized by inter-molecular N-H?N, C-H?O and C-H?N hydrogen bonds. In addition, ?-? stacking is found between the pyridine ring and the pyrazolo-pyrimidin-4-one ring systems, with centroid-centroid distances in the range 3.9627?(12)-4.6781?(12)?Å.
