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

ABSTRACT: 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.

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. ...[more]

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.

Project description:In he title compound, C(13)H(16)N(4)O(3), the pyrazole ring is planar (r.m.s. deviation = 0.054?Å). The pyran ring is not planar; the mean plane makes a dihedral angle of 1.9?(1)° with the pyrazole ring. In the crystal structure, inter-molecular N-H?N and N-H?O inter-actions lead to a linear chain motif.

Project description:In the title compound, C(15)H(9)Cl(2)F(3)N(2)O(2), the 1,6-dihydro-pyrano[2,3-c]pyrazole ring system is almost planar, with a maximum deviation of 0.0226?(14)?Å, and forms a dihedral angle of 69.90?(6)° with the benzene ring.

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].

Project description:In the title compound, C(15)H(14)N(4)O, the pyrazole ring is aligned at 88.23?(4)° with respect to the aromatic ring and at 3.75?(4)° with respect to the pyran ring. In the crystal, N-H?N hydrogen bonds link adjacent mol-ecules into a linear chain motif. C-H?N inter-actions are also observed.

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

Project description:In the title compound, C(14)H(11)ClN(2)O(2), two independent mol-ecules (A and B) comprise the asymmetric unit with the main difference between them being the relative orientation of the pendent phenyl ring with respect to the fused-ring system [dihedral angles = 8.32?(8)° (A) and 28.32?(8)° (B)]. In the crystal, the A mol-ecules are connected into a linear supra-molecular chain along the a axis via C-H?O inter-actions and linked to this via C-H?Cl inter-actions are the B mol-ecules. The chains are connected into layers in the ab plane by ?-? inter-actions between pyrazole (A) and pyran (B) rings, and between pyrazole (B) and pyran (A) rings [centroid-centroid distances = 3.5442?(11) and 3.4022?(10)?Å, respectively].

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?? inter-actions occur, and a slipped ?-? stacking inter-action [centroid-centroid separation = 3.8425?(8)?Å] is also observed.
