A new dinuclear Cd(II)-azido complex of 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (PMT) pincer ligand is synthesized. Its single crystal X-ray structure reveals the [Cd(PMT)(Cl)(N3)]2 formula. The triclinic parameters are a = 9.323(4) Å, b 10.936(5) c 11.312(6) ? 112.637(10)°, ? 104.547(11)° and ? 105.133(10)° while V 944.1(8) Å3. Due to symmetry considerations, asymmetric ...

Bacteria were isolated that could utilize quantitatively the s-triazine herbicide prometryne [N,N' -bis(1-methylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine] or ametryne [N-ethyl-N'-(1-methylethyl)-6-(methylthio)-1,3,5-triazine- 2,4-diamine], or both, as a sole source of sulfur for growth. The success of enrichments depended on previous exposure of the soil inoculum to s-triazine herbicides...

The synthesis and characterization of a novel triazine anion pentafluoroosmium(VI) complex are presented. The single crystal determination of the title compound (hereafter denoted 1) was carried out at −140 ◦C. Compound 1, C3F4N3OsF5, crystallizes in the monoclinic space group, P21/n, with unit cell dimensions: a = 8.6809(17) Å, b = 7.6848(15) Å, c = 12.415(3) Å, β = 102.633(4)◦, V = 808.2(3) Å...

alzheimer's disease (ad) is the most prevalent neurodegenerative disorder. it is characterized by formation of amyloid plaques and neurofibrillary tangles in the brain, degeneration of the cholinergic neurons and neural cell death. this study was aimed to investigate the effect of a triazine derivative, c16h12cl2n3s, on learning in an alzheimer's rat model. animals were divided into seven group...

Anion receptors bearing p electron-deficient arenes have attracted increasing interest during the past decade. The anion–p interaction between charge neutral electron-deficient aromatic rings, as predicted by theoreticians, has been evidenced experimentally both by solid state and solution investigations. For example, in the solid state, while weaks-interaction in which anions interact with p e...

In this work, the degradation of 2-chloro-4,6-diamino-1,3,5-triazine in aqueous solutions by photo-Fenton process has been investigated. The preliminary results have shown that the degradation of 2-chloro-4,6-diamino-1,3,5-triazine by photo-Fenton process is more rapid and more effective than Fenton and UV/H2O2 processes. The effects of certain experimental parameters on kinetics and efficiency...

Herein we report a parallel solid-phase synthesis of 1,3,5-triazine based nucleoside analogues by a three-step substitution, starting from 2,4,6-trichloro-1,3,5-triazine. A library of 80 galactosyl-1,3,5-triazine compounds was prepared in high purity without extensive reaction conditions or tedious purification, suggesting the generality of this method.

6-Methyl-2-phenyl-7H-Oxazolo [3,2-b] [1,2,4] triazine (1) undersent ting transformation on treatment with ammonia and primary amines to afford the corresponding imidazol [1,2-b][1,2,4] triazine (2). Treatment of (1) with hydrazine hydrate gave the corresponding 3-aryl-4H-1,2,4- triazino [4,3-b][1,2,4] triazin-8 (1H)-one (3).
