THE TITLE COMPOUND [SYSTEMATIC NAME: 4,6-di-chloro-N-(2-chloro-phen-yl)-1,3,5-triazin-2-amine], C9H5Cl3N4, is a triazine fungicide. The dihedral angle between the planes of the triazine and benzene rings is 4.04 (8)°. In the crystal, two weak C-H⋯N hydrogen bonds and short Cl⋯Cl contacts [3.4222 (4) Å] link adjacent mol-ecules, forming two-dimensional networks parellel to the (112) plane. The p...

The synthesis, characterization, and host-guest chemistry of high-generation triazine dendrimers are described. With pyrene and camptothecin as guests, experiments revealed that the guest capacity of odd-generation triazine dendrimers increased until generation 7 but decreased at generation 9. Molecular dynamics simulations conducted in explicit solvent showed a useful fingerprint for this beha...

In the crystal, C(20)H(15)N(7)O(6)S, the dihedral angle between the oxadiazole and triazine rings is 86.94 (7)°. The oxadiazole ring makes a dihedral angle of 52.96 (8)° with the phenyl ring, while the triazine ring makes a dihedral angle of 82.08 (7)° with the benzene ring. In the structure, mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming an inversion dimer. The dimers are fur...

A procedure for immobilization of well-defined quantities of oligodeoxyribonucleotides (ODNs) to a versatile nylon support is described. The solid support, a nylon-6/6 bead, is covalently coated with poly(ethyleneimine) to provide a reactive spacer-arm for attachment of ODNs. 5'-Aminohexyl-tailed ODNs are selectively activated using 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride) and then co...

In the title compound, C(7)H(9)N(5)O(2)S, the pyrazolo-[4,3-e][1,2,4]triazine fused-ring system is essentially planar [maximum deviation = 0.0420 (3) Å]. In the crystal, mol-ecules related by twofold axes are linked into a mol-ecular net via inter-molecular C-H⋯O and C-H⋯N hydrogen bonds. π-π inter-actions are observed between the triazine and pyrazole rings of mol-ecules related by the the two...

Eleven compounds have been synthesized in a series of [1, 3, 5] triazine analogues which, in addition to 4-amino benzonitrile, contain 8-hydroxy quinoline and different piperazines as well as piperidine substituents on the C-6 position of s-triazine ring. The title compounds were then evaluated for their in vitro microbial activity against 2 gram –Ve bacteria (E.coli, P. aeruginosa), 2 gram +Ve...

In the title compound, C(10)H(12)N(6), the two 5,6-dimethyl-1,2,4-triazine halves of the mol-ecule are related by a centre of symmetry. The two triazine rings are coplanar to within a maximum deviation of 0.013 (2) Å from the mean plane of the ring atoms. In the crystal, mol-ecules form layers parallel to the (100) crystallographic plane. Adjacent layers are held together via a C-H⋯π inter-acti...
