Resumen
This work presents a study related to the synthesis and structural analysis of
coordination polymers and molecular compounds derived from Hg(TeAr)2. Was used
as starting reagents some Hg(TeAr)2, considered basic building blocks for synthesis
inorganic, and dithioligands of the type carbamate and phosphate, since they are
extremely versatile in complexation to transition elements. The compounds obtained
were: [Hg(TePh)(S2CNEt2)]n (1), [Hg(TePh){S2P(OEt)2}]n (2), [Hg(TePh)(S2CNC4H8)]n
(3), [Hg2(Tedmb)2(S2CNC4H8)2]n (4), [Hg(dmb)(S2CNC4H8)] (5),
[Hg(Temes)(S2CNC4H8)]n (6) e [Hg(mes)(S2CNC4H8)] (7), being can perform a
structural study all these compounds, using as the main tool method the X-ray
diffraction in sigle crystal, in addition to infrared spectroscopy and elementar
analysis. Based on the structural analysis of these compounds can be concluded that
the organization of crystal packing and the formation of supramolecular structures
depends largely on the choice of appropriate ligands, being can thus control over the
coupling between the minimum units generated, making possible to obtain systems
really polymeric or molecular.
