2-(4-Chloro-phen-yl)-4-phenyl-1,2-di-hydro-quinazoline.

ABSTRACT: In the title compound, C20H15ClN2, the pyrimidine ring is in a flattened half-chair conformation. The phenyl and chloro-substituted benzene rings form dihedral angles of 84.97?(5) and 80.23?(4)°, respectively, with the benzene ring of the di-hydro-quinazoline group. The dihedral angle between the phenyl and chloro-substituted benzene rings is 61.71?(5)°. In the crystal, mol-ecules are arranged in inter-secting layers parallel to (101) and (-102), with N-H?N hydrogen bonds linking mol-ecules along [010]. In addition, a weak C-H?? inter-action is observed.

Crystal structures of three 1-oxo-1,2-di-hydro-naphthalene derivatives: dimethyl 4-(4-meth-oxy-phen-yl)-2-(4-methyl-phen-yl)-1-oxo-1,2-di-hydro-naphthalene-2,3-di-carboxyl-ate, dimethyl 1-oxo-2-(pyren-4-yl)-4-(thio-phen-2-yl)-1,2-di-hydro-naphthalene-2,3-di-carboxyl-ate and ethyl 1-oxo-2-phenyl-2,4-bis-(thio-phen-2-yl)-1,2-di-hydro-naphthalene-3-carboxyl-ate.

Project description:In the title 1-oxo-1,2-di-hydro-naphthalene derivatives, C28H24O6, (I), C34H22O5S, (II), and C27H20O3S2, (III), the cyclo-hexa-1,3-diene rings of the 1,2-di-hydro-naphthalene ring systems adopt half-chair, boat and half-chair conformations, respectively. The carbonyl O atoms attached to the di-hydro-naphthalene ring systems are each significantly deviated from the mean plane of the 1,2-di-hydro-naphthalene ring system, by 0.6162?(12)?Å in (I), 0.6016?(16)?Å in (II) and 0.515?(3)?Å in (III). The mean planes of the 1,2-di-hydro-naphthalene ring systems make dihedral angles of 85.83?(3), 88.19?(3) and 81.67?(8)°, respectively, with the methyl-phenyl ring in (I), the pyrene ring in (II) and the phenyl ring in (III). In (I), the mol-ecular structure is stabilized by an intra-molecular C-H?O hydrogen bond, generating an S(6) ring motif. In the crystal of (I), mol-ecules are linked by an inter-molecular C-H?O hydrogen bond, which generates a C(8) zigzag chain running along [100]. Adjacent chains are further connected by C-H?? and offset ?-? inter-actions [centroid-centroid distance = 3.6572?(9)?Å], forming a double-chain structure. In the crystals of (II) and (III), mol-ecules are linked into chain structures by offset ?-? inter-actions with centroid-centroid distances of 3.5349?(12) and 3.8845?(13)?Å for (II) and 3.588?(2)?Å for (III). In (II) and (III), the thio-phene rings are orientationally disordered over two sites, with occupancy ratios of 0.69:0.31 for (II), and 0.528?(4):0.472?(4) and 0.632?(5):0.368?(5) for (III).

Project description:The title compounds, C13H8ClN3O6, (I), and C13H9N3O6, (II), differ in the orientation of the two aromatic rings. In (I), they are essentially coplanar, making a dihedral angle of 8.2 (1)°, while in (II), they are inclined to one another by 76.2 (1)°. The two nitro groups are essentially coplanar with the attached benzene rings, as indicated by the dihedral angles of 1.4 (2) and 2.3 (2)° in (I), and 4.96 (18) and 5.4 (2)° in (II). The carbamate group is twisted slightly from the attached benzene ring, with a C-N-C-O torsion angle of -170.17 (15)° for (I) and 168.91 (13)° for (II).
