“…Upon further heating, complex 1 shows a quick weight loss in the temperature range of 230–335 °C, which is due to the decomposition of the organic frameworks. The continuous weight loss occurring at above 335 °C may correspond to the evaporation of HgCl 2 [34] . Similarly, complex 2 begins to decompose at above 230 °C with a sharp weight loss, which is accompanied by the elimination of HgCl 2 .…”

Two complexes, [HgL 1 Cl 2 ] n (1) and [Hg 2 (L 2) 2 Cl 4 ] n (2), have been synthesized and characterized from two dipyridylamide ligands (L 1 and L 2) with mercury(II) chloride, respectively. The two complexes exist as 1D coordination polymers but exhibit different architectures with slightly adjusted 3-and 4-position of nitrogen atom in the pyridyl rings from the two ligands. In complex 1, the mercury(II) center is four-coordinated with distorted tetrahedral geometry in 1D-chain structures. In complex 2, the mercury(II) center is five-coordinated with distorted square pyramidal geometry in the 1D-looped structures. The thermal stabilities and vapor adsorption properties of the two complexes were investigated as well.

“…In our research, we have investigated benzoylthioureas, which are compounds with a wide range of applications. Possessing a thiocarbonyl group, 1-acylthioureas easily form coordination complexes with soft Lewis acids, such as mercury (Esté vez-Herná ndez et al, 2015;Okuniewski et al, 2015;Rosiak et al, 2018a;Hu et al, 2016) or copper (Wang et al, 2017) ions. Due to the simultaneous presence of the carbonyl group and the thiourea core, they have interesting coordination properties which enable various chemical and biochemical applications.…”

By the reaction of benzoyl chloride, potassium isothiocyanate and the appropriate halogenoaniline, i.e. 2/3/4-(bromo/iodo)aniline, we have obtained five new 1-benzoyl-3-(halogenophenyl)thioureas, namely, 1-benzoyl-3-(2-bromophenyl)thiourea and 1-benzoyl-3-(3-bromophenyl)thiourea, C14H11BrN2OS, and 1-benzoyl-3-(2-iodophenyl)thiourea, 1-benzoyl-3-(3-iodophenyl)thiourea and 1-benzoyl-3-(4-iodophenyl)thiourea, C14H11IN2OS. Structural and conformational features of the compounds have been analyzed using X-ray diffraction and theoretical calculations. The novel compounds were characterized by solid-state IR and 1H/13C NMR spectroscopy. The conformations and intermolecular interactions, such as hydrogen bonds, π–π and S(6)...π stacking, and X...O (X = I or Br), I...S and I...π, have been examined and rationalized, together with four analogous compounds described previously in the literature. The set of nine compounds was chosen to examine how a change of the halogen atom and its position on the phenyl ring affects the molecular and crystal structures.

“…ese benzoylthiourea derivatives (BTU) proved to have excellent properties to bind to various metal ions due to the very strong donor groups (carbonyl and thioamide) that yield various transition metal complexes. e BTU ligands can give neutral homoleptic or heteroleptic complexes either with S-and Ocoordination, when the ligand is coordinated in monoanionic bidentate form by deprotonation or with only S-coordination if the ligand is bound in neutral form to the metal center [22][23][24][25][26][27][28][29][30][31][32].…”

Mesomorphic three-coordinate copper(I) complexes ([Cu(BTU) 2 X], where X � Cl or Br) based on a new N-benzoylthiourea (BTU) ligand with two decyloxy and one perfluorooctyl groups at its periphery were designed and prepared. e BTU ligand coordinates via the S atom in a neutral monodentate fashion as confirmed by IR and NMR spectroscopy data. e liquid crystalline behavior of these copper(I) complexes was investigated by a combination of polarized optical microscopy (POM), differential scanning calorimetry (DSC), and X-ray diffraction analysis (XRD), while their thermal stability was studied by thermogravimetric analysis (TGA). ese new copper(I) complexes have mesomorphic properties and exhibit a hexagonal columnar mesophase over a large temperature range, more than 100°C.
