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

ABSTRACT: 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.

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⋯π and π-π inter-actions [centroid-centroid separation = 3.6374 (12) Å] further consolidate the packing. ...[more]

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].

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.

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].

Project description:The title compound, C(30)H(28)N(6)O(2), is a symmetric diimine derived from ortho-dibenzaldehyde. Both C=N bonds are (E)-configured. The terminal N-bonded phenyl groups adopt staggered conformations relative to their respective parent heterocycles, the relevant least-squares planes inter-sect at angles of 32.35?(11) and 38.59?(10)°. In the crystal, C-H?O contacts connect the mol-ecules into chains along the b axis and give rise to a C(1) (1)(14)C(1) (1)(14) and a R(2) (2)(12) pattern on different levels of graph-set analysis. The shortest inter-centroid distance between two centroids was found at 4.2074?(11)?Å between the two five-membered heterocycles.

Project description:The title Schiff base compound, C(23)H(23)N(5)O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl-pyrazole-4-carbaxaldehyde. The mol-ecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H?O hydrogen bond generates an S(6) ring motif.

Project description:In the title compound, C19H17Cl2N3O2, there are three mol-ecules (A, B and C) in the asymmetric unit and each differs in the conformation adopted. As a result of steric repulsion, the amide group is rotated with respect to both the dichloro-phenyl and 2,3-dihydro-1H-pyrazol-4-yl rings, making dihedral angles of 44.5?(2) and 56.2?(2)°, respectively in A, 51.1?(2) and 54.1?(2)° in B, and 53.8?(2) and 54.6?(2)° in C. The dihedral angles between the dichloro-phenyl and 2,3-dihydro-1H-pyrazol-4-yl rings are 54.8?(2), 76.2?(2) and 77.5?(2)° in mol-ecules A, B and C, respectively, while the 2,3-dihydro-1H-pyrazol-4-yl and phenyl rings make dihedral angles of 45.3?(2), 51.2?(2) and 42.8?(2)°, respectively. In the crystal, two of the mol-ecules are linked through N-H?O hydrogen bonding to an adjoining mol-ecule, forming dimers of the R2(2)(10) type, while the third mol-ecule forms such dimers with itself. C-H?O inter-actions link the dimers.
