In the title centrosymmetric binuclear Ag(I) complex, [Ag(2)(NO(3))(2)(C(12)H(10)N(4))(2)], each Ag(I) center is coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 2-(3-pyridylmeth-yl)-2H-benzotriazole (L) ligands, and an O atom of a coordinated NO(3) (-) anion in a distorted T-shaped geometry. This forms a unique box-like cyclic dimer with an intra-molecula...

The title compound, C6H4ClN3, is essentially planar, with a maximum deviation of 0.007 (3) Å. In the crystal, a short contact of 2.818 (3) Å is observed between N and Cl atoms of adjacent mol-ecules.

The asymmetric unit of the title compound, (C(6)H(6)N(3))[CoCl(3)(C(6)H(5)N(3))]·H(2)O, contains two crystallographically independent cations, two anions and two water mol-ecules. The structure has been reported previously [Zhang, Li, Wang, Xie, Wang & Shen (2004 ▶). Acta Cryst E60, m498-m500] as a neutral cobalt(III) complex accompanied by unprotonated benzotriazole mol-ecules and here has bee...

Ethyl-1H-benzotriazol-1-acetate 2 was prepared by reacting 1H-benzotriazole 1 in alcohol with ethyl bromoacetate in presence of anhydrous potassium carbonate, which was treated with hydrazine hydrate under reflux for 1824 hours to obtain the intermediate 1H-benzotriazole-1-acetic acid hydrazide 3. This compound on Schiff’s reaction with aromatic aldehydes in presence of solvent mixture yielded ...

The environmental fate and effects of triazoles and benzotriazoles are of concern within the context of chemical regulation. As part of an intelligent testing strategy, experimental tests were performed on endpoints that are relevant for risk assessment. The experimental tests included the assessment of ecotoxicity to an alga, a daphnid and zebrafish embryos, and the assessment of ready biodegr...

The structures of 1-trimethylsilyl-1,2,3-benzotriazole and 2-trimethylsilyl-1,3-thiazole have been determined by gas electron diffraction and computational methods. While 1-trimethylsilyl-1,2,3-benzotriazole shows a significant asymmetry in the way the SiMe(3) groups bonds to the ring system, the same is not true for 2-trimethylsilyl-1,3-thiazole. However, it has been shown that when the positi...

In the title compound, C(12)H(11)N(3)O(2), the benzotriazole ring system is approximately planar [maximum deviation = 0.008 (1) Å] and its mean plane is oriented at a dihedral angle of 24.05 (4)° with respect to the furan ring. In the crystal, O-H⋯N hydrogen bonds link the mol-ecules into chains along the ac diagonal. π-π stacking between the furan rings, between the triazole and benzene rings,...
