The mol-ecular structure of the title compound, C20H16N6, contains two benzotriazole units bonded to a benzene nucleus in a meta configuration, forming dihedral angles of 88.74 (11) and 85.83 (10)° with the central aromatic ring and 57.08 (9)° with each other. The three-dimensional structure is controlled mainly by weak C-H⋯N and C-H⋯π inter-actions. The mol-ecules are connected in inversion-re...

The protection of metallic surface is commonly done with zinc phosphate in acid aqueous phosphate solutions containing zinc ions and phosphoric acid, as well in addition of other metallic ions (nickel, chromium, calcium, niobium etc.), in presence of accelerators as nitrate ions, hydroxylamine sulfate, benzotriazole and others. The present article is a study on the surface structure of zinc pho...

Sequential Monte Carlo and quantum mechanical calculations of the electronic polarization of the ground and first vertical excited states of 1H-benzotriazole in water are made. Using statistically uncorrelated configurations and CASSCF ab initio calculations the increase in the ground and excited state dipole moments of 1Hbenzotriazole from gas phase to aqueous environment are obtained as 2.89 ...

In the title compound, C(19)H(15)Cl(2)N(3)O(2), the benzotriazole ring system is approximately planar [maximum deviation = 0.018 (2) Å] and its mean plane is oriented at dihedral angles of 30.70 (5) and 87.38 (4)°, respectively, to the furan and benzene rings while the dihedral angle between furan and benzene rings is 74.46 (6)°. In the crystal, weak C-H⋯N hydrogen bonds link the mol-ecules int...

In the title mol-ecule, C(21)H(17)Cl(2)N(3)O, the benzotriazole ring is oriented at dihedral angles of 48.72 (6) and 62.94 (5)°, respectively, to the phenyl and benzene rings and the dihedral angle between the phenyl and benzene rings is 88.95 (6)°. In the crystal, weak C-H⋯N hydrogen bonds link the mol-ecules into chains. π-π contacts between the triazole and benzene rings [centroid-centroid d...
