5-(Anthracen-9-yl)-3-(4-nitro-phen-yl)-1-phenyl-4,5-dihydro-1H-pyrazole.

ABSTRACT: In the title compound, C(29)H(21)N(3)O(2), the five-membered pyrazoline ring is nearly planar, the maximum deviation being 0.037?(3)?Å. The anthracene ring system is approximately perpendicular to the central pyrazoline ring, making a dihedral angle of 86.55?(16)°, whereas the two attached benzene rings are oriented at smaller dihedral angles of 12.9?(2) and 14.7?(2)°with respect to the pyrazoline ring. An intra-molecular C-H?N hydrogen bond is observed.

In the title compound, C(29)H(21)N(3)O(2), the five-membered pyrazoline ring is nearly planar, the maximum deviation being 0.037 (3) Å. The anthracene ring system is approximately perpendicular to the central pyrazoline ring, making a dihedral angle of 86.55 (16)°, whereas the two attached benzene rings are oriented at smaller dihedral angles of 12.9 (2) and 14.7 (2)°with respect to the pyrazoline ring. An intra-molecular C-H⋯N hydrogen bond is observed. ...[more]

1-[5-(Anthracen-9-yl)-3-(4-nitro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethan-1-one.

Project description:In the title compound, C(25)H(19)N(3)O(3), steric repulsion between the methine H atom and one of the anthryl H atoms seems to be concomitant with the considerable distortion of the anthryl fragment from planarity. The side rings of the anthryl subtend an angle of 9.57?(8)°, which is an extreme value among the known reliably determined structures. This angle correlates with the length of the bond by which the anthryl is attached to the rest of the mol-ecule. In the anthryl fragment, the maximum deviation of one of the C atoms from the mean plane is 0.126?(3)?Å and regards the carrier C atom involved in the repulsion between the anthryl and the methine H atoms. The inter-planar angle between the pyrazoline ring and the anthryl fragment is 88.36?(5)° and that between the pyrazoline and 4-nitro-phenyl rings is 8.80?(15)°. Weak inter-molecular C-H?N, C-H?? and ?-? inter-actions [centroid-centroid distances of 3.7659?(17), 3.9477?(15) and 3.8972?(15)?Å] are pesent in the structure.

Project description:In the title compound, C(25)H(20)N(2)O, the pyrazoline ring is nearly planar [maximum atomic deviation = 0.0254?(17)?Å]; but the anthracene ring system is distorted from a coplanar structure [maximum atomic deviation = 0.181?(3)?Å], the dihedral angle between the outer benzene rings being 10.68?(13)°. The pyrazoline ring is almost perpendicular to the mean plane of the anthracene ring system [dihedral angle = 76.94?(8)°], but nearly coplanar with the phenyl ring [dihedral angle = 1.63?(7)°]. ?-? stacking is observed between parallel benzene rings of adjacent anthracene units, the face-to-face distance being 3.27?(3)?Å. Weak intra-molecular C-H?N hydrogen bonding also occurs.
