Silver complexes triazines

The synthesis of cahx[4]arene dimelamines with different functionalities and their self-assembly with barbituric and cyanuric acid to hydrogen-bonded nanostructures have been published <05OBC3727> Unique ionophores of penta-crown ethers have been prepared by the reaction of l,3,5-triacryloylhexahydro-l,3,5-triazine (TAHTA) with diaza 18-crown-6 followed by Michael addition, and their binding capabilities towards alkali metal cations studied <05SL2257>. New silver complexes of polydentate ligands including a derivative of pyrazol-l-yl-l,3,5-triazine have been reported <05EJ14370>. 

Oxidation of 2,3-diphenyl-l,2,5,6-tetrahydro-l,2,4-triazine (251) with dibenzoyl peroxide or bromine gives the 2,5-dihydro derivative (252) (Equation (29)). 1,3-Diphenyl-1,2,5,6-tetrahydro-1,2,4-triazine (253) forms a silver complex with silver oxide, which is oxidized by dilute nitric acid to the... 

Complexes 123-131 were obtained by the direct reaction of the corresponding triazine and different silver salts according to Eq. (13). These products are sparingly soluble in acetone and insoluble in other conventional organic solvents. 

Slow diffusion of the triazine and the silver salt solutions afforded monocrystals suitable for X-ray diffraction in the cases of complexes 124,125 and 127. Compounds 124 and 127 have structures that are practically identical and only the latter will be discussed. Figure 3.15 gives a representation of complex 125.
