“…Numerous complexes (Bu et al, 2002(Bu et al, , 2003Sun et al, 2012) were prepared by the reaction of aliphatic or aromatic thioethers with different metal ions, e.g. the reaction of thianthrene (TA) with AuCl 3 in the presence of liquid SOCl 2 (Tjahjanto & Beck, 2009); the product was a black crystalline solid with square-planar geometry for both ions, i.e. dichloridobis(thianthrene)gold(III) tetrachloridoaurate(III).…”

Silver nitrate reacts with 6-methylmercaptopurine riboside (6-MMPR) in aqueous solution containing methanol and dimethyl sulfoxide at room temperature to give a colourless crystalline complex, namely, bis(6-methylmercaptopurine riboside-κN 7)(nitrato-κ2 O,O′)silver(I) 2.32-hydrate, [Ag(NO3)(C11H14N4O4S)2]·2.32H2O. The crystal structure, determined from synchrotron diffraction data, shows a central AgI ion on a crystallographic twofold rotation axis, coordinated in an almost linear fashion by two 6-MMPR ligands via atom N7 (purine numbering), with the nitrate counter-ion loosely coordinated as a bidentate ligand, forming a discrete molecular complex as an approximate dihydrate. The complex and water molecules are connected in a three-dimensional network by hydrogen bonding.

“…TT is a nonplanar heterocycle bent by sulfur. When developing sulfur-rich π-electron systems, it is important to attain remarkable electrochemical [60][61][62][63][64], photophysical [65][66][67], and molecular dynamics properties [68,69]. Parola et al (2007) successfully synthesized the smallest family, thiacalix [2]-1,9-thianthrene (Figure 1 (left)), which was bridged at the 1,9-positions of the TT unit, from a thiacalix [4]arene derivative under high-temperature [70].…”

Synthesis, Structure, and Characterization of Thiacalix[4]-2,8-thianthrene

Sulfur-containing macrocycles have attracted substantial interest because they exhibit unique characteristics due to their polygonal ring-shaped skeleton. In this study, a thianthrene-based cyclic tetramer with the sulfur linker, thiacalix[4]-2,8-thianthrene (TC[4]TT), was successfully prepared from a cyclo-p-phenylenesulfide derivative using acid-induced intramolecular condensation. Single crystal X-ray diffraction revealed that TC[4]TT adopts an alternative octagonal form recessed to the inner side. Its internal cavity included small solvents, such as chloroform and carbon disulfide. Due to its polygonal geometry, TC[4]TT laminated in a honeycomb-like pattern with a porous channel. Furthermore, TC[4]TT showed fluorescence and phosphorescence emission in a CH2Cl2 solution at ambient and liquid nitrogen temperatures. Both emission bands were slightly redshifted compared with those of the reference compounds (di(thanthren-2-yl)sulfane (TT2S) and thianthrene (TT)). This work describes a sulfur-containing thiacalixheterocycle-based macrocyclic system with intriguing supramolecular chemistry based on molecular tiling and photophysical properties in solution.

“…Thus, we attempted the synthesis of digold(I) complexes with polyaromatic ligands in order to stabilize the U-shaped structure by the π–π interaction of the two aromatic ligands.

A series of digold complexes possessing two thianthrenyl ligands, Au 2 (Thi) 2 (Ph 2 P(CH 2 ) n PPh 2 ) (Thi: 1-thianthrenyl; 1 : n = 1, 2 : n = 2, 3 : n = 3, 4 : n = 4), were prepared and characterized by crystallographic and spectroscopic measurements. X-ray crystallography of complexes 1 and 3 revealed U-shaped structures with short Au–Au distances [3.2171(3) Å and 3.0735(2) Å]. Complex 2 and three of the four structure-determined molecules of complex 4 showed structures without Au–Au contacts. UV–vis spectroscopic measurements of 1 – 4 and TD-DFT calculations of the two conformers of 1 revealed that complexes 1 and 3 in the solution phase contained conformers with Au(I)–Au(I) interactions in a much higher proportion than complexes 2 and 4 . As a result, complexes with diphosphine ligands containing an odd number of methylene groups preferred structures with Au–Au interactions in the solid state and in solution. Oxidation of 1 with 2 equiv of PhICl 2 yielded a mixture of monomeric and dimeric thianthrenes and its dimer via ligand elimination and C–C coupling, respectively.
