In the title mol-ecule, C(23)H(14)N(4)O, the dihedral angle between the pyridine rings of the phenanthroline unit is 4.43 (8)° and the dihedral angle formed by the nine essentially planar [maximum deviation 0.0389 (16)Å] non-H atoms of the benzimidazole unit and the naphthalene ring system is 74.22 (5)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N and O-H⋯N hydrogen bonds, fo...

The title mol-ecule, C17H11FN2O3, is nearly planar [maximum deviation = 0.197 (1) Å] and the mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond forming an S(6) ring motif. The H atom of the intra-molecular hydrogen bond was found to be disordered over two sites and thus both the hy-droxy and keto tautomers are simultaneously present in the solid. Refinement of the occupancy of this...

Magnetic Cellulose/Fe3O4/Co3O4 nanocomposite as a new catalyst was synthesized and characterized by FT-IR, XRD, TGA, SEM, TEM, ICP-AES and VSM techniques. The catalytic activity of this heterogeneous catalyst was studied through one-pot synthesis of 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives from three component reactions of aromatic aldehydes, 2-aminobenzothiazole,...

The solid state structure of 1-((1H-benzotriazol-1-yl)methyl)naphthalen-2-ol, C17H13N3O, shows that this Mannich base crystallizes forming intermolecular N...HO hydrogen bonds, rather than intramolecular ones. Factors contributing to this choice of hydrogen-bonding mode are discussed. The compound crystallizes in the monoclinic system, P2(1)/c space group, with lattice constants: a = 11.7934(9)...
