2-Meth­oxy-6-(6-methyl-1H-benzimid­azol-2-yl)phenol

In the title mol-ecule, C(15)H(14)N(2)O(2), the substituted benzene ring forms a dihedral angle of 4.15 (1)° with the benzimidazole ring system. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the solid state, mol-ecules are linked into chains along the [001] via inter-molecular bifurcated N-H⋯(O,O) hydrogen bonds, which generate R(1) (2)(5) ring motifs. The crystal pack...

(E)-2-[(6-Ethoxy­benzothia­zol-2-yl)imino­meth­yl]-6-methoxy­phenol

In the title mol-ecule, C(17)H(16)N(2)O(3)S, the benzothia-zole fragment and the benzene ring form a dihedral angle of 13.8 (4)°, and an intramolecular O-H⋯N hydrogen bond occurs. In the crystal structure, pairs of weak inter-molecular O-H⋯S and C-H⋯(O,O) hydrogen bonds link mol-ecules into centrosymmetric dimers. These dimers are related by translation along the a axis and form stacks via π-π ...

2-Meth­oxy-6-(6-methyl-1H-benzimidazol-2-yl)phenol

The mol-ecule of the title compound, C(15)H(14)N(2)O(2) is almost planar, the dihedral angle between the 6-methyl-1H-benz-imidazole plane and the 2-methoxy-phenol plane being 6.9 (2)°. An intra-molecular O-H⋯N hydrogen bond is present. Adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a three-dimensional network structure. The benzoimidazole methyl group and its attached C atom are po...

1-[6-(6-Acetyl­pyridin-2-yl)pyridin-2-yl]ethanone

In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63 (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular sheet paral...
