13. AVALIAÇÃO DE ARRANJOS SUPRAMOLECULARES DE COMPLEXOS TRIAZENIDOS DE MERCÚRIO(II) E COBRE(II) / EVALUATION OF SUPRAMOLECULAR ARRANGEMENTS OF TRIAZENIDE COMPLEXES OF MERCURY(II) AND COPPER(II).
The reaction between deprotonated 1,3-Bis(3-acetylphenyl)triazene and Hg(CH3COO)2 in methanol, yields [Hg(RNNNR)(Py)] (R=3-CH3C(O)C6H4) (1), a triazenide dimeric mononuclear complex of mercury(II). The crystal structure analysis of (1) reveals a bi−dimensional supramolecular arrangement as result of molecular self-assembly provided by Hg−η,

16. INVESTIGAÇÃO DE COMPLEXOS BINUCLEARES DE K+ E CU(II) COM LIGANTES 1,3-DIARILTRIAZENIDOS SIMÉTRICOS / COMPLEXES INVESTIGATION BINUCLEARES OF K+ And Copper(II) WITH 1,3-DIARYLTRIAZENES AS LIGANDS SYMMETRICAL
At work present it synthesized and determined itself the molecular structure of a copper complex (II) and another of potassium in which both involve triazenides ligands monocatenados previously deprotonated. The reaction between hydroxide of solid potassium and it pre-ligand 1,3-bis(4-nitrophenyl)triazene, in methanol, originated the triazenide complex [K(O2
