Dinuclear and polymeric Hg(II) complexes with 1-(2-furoyl)thiourea derivatives: Their crystal structure and related properties

“…The This is in accordance with the findings on most of the thiourea complexes reported [29,30,65]. In addition to the frequency, the vibration shows a 25 significant intensity decrease, which is also an evidence of the coordination bond formation.…”

“…11a) Found: 73.16%). Finally, the two last steps are expected to be a sequential combination of dechlorination, desulfurization and evolution of metallic mercury [65]. Complex HgCl 2 -FBT has polymeric structure.…”

“…Thiourea compounds are very useful building blocks for the synthesis of a wide range of aliphatic macromolecular and heterocyclic compounds [9][10][11]. These compounds are remarkable chelating agents for analytical chemistry and a variety of metal complexes have been described in literature [12][13][14][15][16][17][18]. The presence of hard and soft donor sites in these compounds offers a huge bonding potential since both carbonyl and thiocarbonyl groups can coordinate metallic ions in different manners.…”

“…[9][10][11] These compounds are remarkable chelating agents in analytical chemistry and a variety of metal complexes have been described in the literature. [12][13][14][15][16][17][18] The presence of hard and soft donor sites in these compounds offers a huge bonding potential since both carbonyl and thiocarbonyl groups can coordinate metallic ions in a different manner. Thiourea derivatives usually behave as planar ligands where both S and N atoms are donor sites able to participate in the coordination with the metal center.…”
