6-(2-Hydroxy-phen-yl)-5,6-dihydro-benzimidazolo[1,2-c]quinazolin-12-ium bromide ethanol solvate.

ABSTRACT: In the title compound, C(20)H(16)N(3)O(+)·Br(-)·C(2)H(6)O, the phenol ring forms dihedral angles of 84.5?(1) and 89.3?(1)° with the benzimidazole system and the quinazoline benzene ring, respectively. The two N-H groups act as donors in hydrogen bonds with the bromide ion as acceptor, leading to infinite eight-membered chains along [100]. According to graph-set theory the descriptor on the binary level is C(2) (1)(8). O-H?O and O-H?Br hydrogen bonds also occur.

2-(5,6-Dihydro-benzimidazo[1,2-c]quinazolin-6-yl)phenol.

Project description:The asymmetric unit of the title compound, C(20)H(15)N(3)O, contains two independent mol-ecules, each of which is disordered over two sets of sites corresponding to a rotation of approximately 180° of the dihydro-benzimidazoquinazoline moiety, with refined site occupancies of 0.7479?(13) and 0.2521?(12) for both mol-ecules. The pyrimidine rings are in sofa conformations. In one mol-ecule, the hy-droxy-substituted benzene ring forms dihedral angles of 83.9?(3) and 82.4?(4)° for the major and minor components, respectively, with the mean plane of the benzimidazole ring system. The corres-ponding dihedral angles in the other mol-ecule are 88.31?(14) and 85.8?(6)°. In the crystal, mol-ecules are linked via inter-molecular O-H?N and N-H.·O hydrogen bonds into chains along [100].

2-(5,6-Dihydro-benzimidazo[1,2-c]quinazolin-6-yl)-5-methyl-phenol.

Project description:In the title compound, C(21)H(17)N(3)O, the imidazole ring is essentially planar, with a maximum deviation of 0.009?(1)?Å. The mol-ecule is disordered over two sites corresponding to a rotation of approximately 180° with a refined occupancy ratio of 0.9180?(14):0.0820?(14). The central pyrim-idine ring makes dihedral angles of 5.02?(5), 3.97?(5) and 6.28?(5)°, respectively, with the planes of the imidazole and the terminal phenyl rings for the major component; the values for the minor component are 5.8?(7), 5.0?(6) and 8.5?(6)°, respectively. Part of the observed planarity is accounted for in terms of an intra-molecular N-H?O hydrogen bond. In the crystal, mol-ecules of the major component are connected by O-H?N hydrogen bonds, forming supra-molecular chains along the c axis.

2-(5,6-Di-hydro-benzimidazolo[1,2-c]quinazolin-6-yl)aniline methanol solvate.

Project description:In the structure of the title compound, C(20)H(16)N(4)·CH(4)O, the aniline ring forms dihedral angles of 89.9?(2) and 85.4?(2)° with the benzimidazole and benzene rings, respectively. The orientation of the aniline ring is mainly determined by strong hydrogen bonds between the amino group and the non-fused quinazoline N atom. Inter-molecular hydrogen bonds of the N-H?N-H?N type along [010] and the N-H?O-H?N type along [100] are formed, resulting in C(2) (2)(4) and C(2) (2)(10) descriptors, respectively, on a binary level of graph-set analysis. There are C-H?? contacts with H?? distances of 2.44?Å; however, no ?-stacking is observed.

Project description:In the title solvated benzimidazole compound, C(20)H(15)N(3)O(2)·C(2)H(6)OS, both the benzimidazole fused-ring system and the complete dimethyl sulfoxide solvent mol-ecule are disordered over two sets of sites, in 0.750?(5):0.250?(5) and 0.882?(4):0.118?(4) ratios, respectively. The conformation of the pyrimidine ring is close to a half-chair for the major disorder component, whereas for the minor component it is close to a boat. The dihy-droxy-phenyl ring is almost perpendicular to the mean plane of the benzimidazole ring [dihedral angle = 87.3?(2)° for the major disorder component and 88.3?(5)° for the minor disorder component]. In the crystal, mol-ecules are linked into layers parallel to (110) by O-H?N and C-H?O hydrogen bonds. A bifurcated O-H?(O,S) bond links the benzimidazole and solvent mol-ecules.
