Ethyl 1-(2-hy-droxy-eth-yl)-2-phenyl-1H-benzimidazole-5-carboxyl-ate.

ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C(18)H(18)N(2)O(3). In each one, the benzimidazole ring system is essentially planar, with maximum deviations of 0.027?(1) and 0.032?(1)Å, and makes dihedral angles of 38.64?(6) and 41.48?(6)°, respectively, with the attached benzene rings. An intra-molecular C-H?O hydrogen bond is observed in each mol-ecule. The two independent mol-ecules are connected into a dimer by two inter-molecular O-H?N hydrogen bonds. In the crystal, mol-ecules form a two-dimensional layers parallel to (012) via weak inter-molecular C-H?O hydrogen bonds. In addition, weak ?-? stacking inter-actions are observed with centroid-centroid distances of 3.5244?(12) and 3.6189?(12)?Å.

Ethyl 1-(2-hy-droxy-eth-yl)-2-p-tolyl-1H-benzimidazole-5-carboxyl-ate.

Project description:The asymmetric unit of the title compound, C(19)H(20)N(2)O(3), contains two mol-ecules (A and B) with slightly different orientations of the ethyl groups with respect to the attached carboxyl-ate groups. Intra-molecular C-H?O hydrogen bonds generate S(8) ring motifs in both mol-ecules A and B. In each mol-ecule, the benzimidazole ring system is essentially planar, with maximum deviations of 0.023?(1) and 0.020?(1)?Å, respectively, for mol-ecules A and B. The dihedral angle between the benzimidazole ring system and the phenyl ring is 37.34?(5)° for mol-ecule A and 42.42?(5)° for mol-ecule B. In the crystal, O-H?N and C-H?O hydrogen bonds link the mol-ecules into [100] columns with a cross-section of two-mol-ecule by two-mol-ecule wide, and further stabilization is provided by weak C-H?? and ?-? inter-actions [centroid separations = 3.5207?(7) and 3.6314?(8)?Å].

Project description:In the title compound, C(23)H(25)N(3)O(3), the benzimidazole ring system is essentially planar [maximum deviation = 0.0240 (18) Å].

The pyrrolidine ring is in an envelope conformation with the flap atom disordered over two sites with occupancies of 0.813 (11) and 0.187 (11). In the crystal, weak C-H⋯O hydrogen bonds form R(2) (2)(10) ring motifs, which are connected by further C-H⋯O inter-actions, forming ribbons along the b axis.
