7-(2-Chloro-phen-yl)-2,6,9-trimethyl-dibenzo[b,h][1,6]naphthyridine.

ABSTRACT: In the title compound, C(25)H(19)ClN(2), the dibenzo[b,h][1,6]naphthyridine system is planar to within 0.16 (2) Å, and the chloro-phenyl ring is inclined to it by 82.53 (7)°. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains propagating in [100]. There are also a number of weak π-π stacking inter-actions present [centroid-centroid distances = 3.8531 (1) and 3.7631 (1) Å].

[8-(4-Chloro-benzo-yl)-2,7-dimeth-oxy-naphthalen-1-yl](2,4,6-trimethyl-phen-yl)methanone.

Project description:In the title compound, C(29)H(25)ClO(4), the dihedral angle between the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group is 65.19 (9)°. The dihedral angles between the naphthalene ring system and the benzene rings of the 2,4,6-trimethyl-benzoyl group and the 4-chloro-benzoyl group are 85.66 (8) and 69.48 (8)°, respectively. In the crystal, two types of inter-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯O inter-action are observed. Moreover, there is a short intra-molecular C=O⋯C=O contact of 2.614 (2) Å between the benzoyl substituents.

2,9-Dimethyl-7-phenyl-N-(4-methyl-phen-yl)dibenzo[b,h][1,6]naphthyridin-6-amine.

Project description:The title compound, C(31)H(25)N(3), was synthesized from 6,4',4''-trimethyl-2,4-bis-(N-phenyl-amino)-quinoline and is the first structural example containing a phenyl and phenyl-amino fragment attached to a fused dibenzo[1,6]naphthyridine moiety. The fused tetra-cyclic ring system is essentially planar [r.m.s. deviation = 0.08?(3)?Å]. The phenyl ring and the phenyl-amino group are inclined by 82.68?(6) and 35.31?(5)°, respectively, to the mean plane of the fused tetra-cyclic ring system. A weak intra-molecular N-H??(arene) inter-action may in part influence the conformation of the mol-ecule. In the crystal, mol-ecules are linked by weak inter-molecular C-H?N hydrogen bonds into centrosymmetric dimers. Additional stabilization is provided by weak C-H?? and ?-? stacking inter-actions [centroid-centroid distances = 3.834?(2) and 3.898?(1)?Å].

Project description:In the title compound, C(13)H(15)ClN(2)S, the dihydro-pyrimidine ring is essentially planar, with a maximum deviation from the least-squares plane of 0.122?(3)?Å for the unsubstitued olefinic C atom. The dihedral angle between the dihydro-pyrimidine and benzene rings is 86.62?(13)°. The crystal structure is stabilized by inter-molecular N-H?S hydrogen bonds, which form centrosymmetric dimers arranged along the c axis.

Project description:The dihydro-pyrimidine ring of the title compound, C(13)H(15)ClN(2)S, adopts an envelope conformation with five almost coplanar atoms (r.m.s. deviation = 0.054?Å) and the C atom bearing the two methyl substituents deviating from this plane by 0.441?(2)?Å. The best plane through the five almost coplanar atoms forms a dihedral angle of 89.56?(5)° with the benzene ring. The crystal packing is characterized by centrosymmetric dimers connected by pairs of N-H?S hydrogen bonds.
