چکیده
The crystal and molecular structure of 3,5-bis(Ar,7V-diethylimonium)-l,2,4trithiolane-tetraiododi-/x-iododimercurate(II), (S3 C2N2(C2H 5)4)Hg2I6, has been determined from a single-crystal X-ray dififraction study. The monoclinic unit cell, space group Plijc, with a = 12-574(3), b = 15-777(4), c = 14-560(4) A, and = 90-83(4)°, contains four formula-units. Three-dimensional intensity data were collected on an automatic diffractometer. Atomic parameters were refined by full-matrix least-squares methods to a conventional R value of 0-05 for 1380 independent non-zero reflexions. The structure consists of (3,5-bis(7V,iV-diethylimonium)-l,2,4-trithiolane)2+ and Hg2I§_ ions. The cation contains a fivemembered ring, S—S—C—S—C, which can be formed by oxidation of dithiocarbamato and thiuramdisulfide complexes.

4-Benzyl-1,2,4-triazin-3,5(2H,4H)-dione (3-benzyl-6-azauracil, 2), and 2,4-dibenzyl-1,2,4-triazin-3,5(2H,4H)-dione (1,3-dibenzyl-6-azauracil, 3) were synthesized by the reaction of 1,2,4-triazin-3,5(2H,4H)-dione (6-azauracil, 1) with benzyl bromide and potassium carbonate in dry acetone via the 18-crown-6-ether catalysis. In these reaction methods, we developed more convenient and efficient met...
