1,3-Diphenyl-3,4-dihydro-benzo[b][1,6]naphthyridine.

ABSTRACT: The title compound, C(24)H(18)N(2), is the first structural example containing the 3,4-dihydro-benzo[b][1,6]naphthyridine fragment. It was synthesized from 2,4,6,8-tetra-phenyl-3,7-diaza-bicyclo-[3.3.1]nonan-9-one and was crystallized from a methanol-ethanol solution over two years as a racemate. The C=N double bond [1.2868?(15)?Å] is bent significantly out of the plane of the aromatic bicyclic ring system [N-C-C-C = -157.63?(12)°] and out of the plane of the phenyl ring bonded at the 1-position [N-C-C-C = 41.15?(16)°].

Project description:In the title pyrazolone derivative, C(15)H(12)N(2)O, the five-membered ring is approximately planar (r.m.s. deviation = 0.018 Å), and the N- and C-bound benzene rings are inclined to this plane [dihedral angles = 21.45 (10) and 6.96 (10)°, respectively] and form a dihedral angle of 20.42 (10)° with each other. Supra-molecular layers are formed in the crystal structure via C-H⋯O and C-H⋯N inter-actions, and these are assembled into double layers by C-H⋯π and π-π inter-actions between the pyrazole and C-bound benzene rings [ring centroid-centroid distance = 3.6476 (12) Å]. The double layers stack along the a axis being connected by π-π inter-actions between the N- and C-bound benzene rings [ring centroid-centroid distance = 3.7718 (12) Å].

1-[4-(4-Chloro-phen-yl)piperazin-1-yl]-3-(6-oxo-3,4-diphenyl-1,6-dihydro-pyridazin-1-yl)propan-1-one.

Project description:In the title compound, C(29)H(27)ClN(4)O(2), the six-membered ring of the pyridazine group is nearly planar [maximum deviation = -0.062 (2) Å] and its mean plane makes dihedral angles of 43.05 (9), 44.71 (10) and 72.57 (9)°, respectively, with the two phenyl and benzene rings. The piperazine ring has a chair conformation and its mean plane is almost perpendicular to the attached benzene ring, with a dihedral angle of 83.20 (16)°. In the crystal, mol-ecules are linked via two pairs of C-H⋯O inter-actions, which result in the formation of chains propagating along [10-1]. Neighbouring chains are linked via C-H⋯π inter-actions.

2,4-Diphenyl-6-trifluoro-methyl-2,3-dihydro-1H,5H-pyrrolo-[3,4-c]pyrrole-1,3-dione.

Project description:The asymmetric unit of the title compound, C(19)H(11)F(3)N(2)O(2), contains two crystallographically unique mol-ecules which differ in the rotation of a phenyl ring and a -CF(3) substituent. The dihedral angles involving the pyrrole ring and the attached phenyl ring are 62.82?(8) and 71.54?(7)° in the two molecules. The difference in the rotation of the CF(3) groups with respect to the pyrrolo rings to which they are attached is 23.5(1)°.

In the crystal, N-H?O inter-actions connect adjacent mol-ecules into a chain normal to (01[Formula: see text]). Crystallographically unique mol-ecules alternate along the hydrogen-bonded chains.
