[Cyclotetrakis-μ3(η2-S,η1-N)-(1,3-thiazolidine-2-thionato)-bis-(η1-S)-(1,3-thiazolidine-2- thione)tetracopper(I)]: electrochemical synthesis, characterization and crystal structure at 160 K

Synthesis of novel chiral Cu or Ag/S,N cluster complexes and absolute stereostructures as determined by x‐ray crystallography

“…10 Its crystal structure is very different from that of 3 having an "open-butterfly' configuration with Cu-Cu distances and angles in the range 2.8887(15)-3.8357(16) Å and 47.51(3)-78.27(4)°, respectively. We also confirmed that, under the normal organic reaction conditions mentioned above, no corresponding metal complex could be formed by the reaction of 1,3-thiazolidine-2-thione 4 with CuCl (Scheme 3).…”

“…Concerning Cu/S,N metal complex, in 1998 Raper et al reported the crystal structure of a [cyclo{tetrakis-µ 3 ( 2 -S, 1 -N)-(1,3-thiazolidine-2-thionato)-bis-( 1 -S)-(1,3thiazolidine-2-thione)tetracopper(I)} from the electrochemical synthesis using 2-mercaptothiazoline 4 and ARgrade metallic copper. 10 Its crystal structure is very different from that of 3 having an "open-butterfly' configuration with Cu-Cu distances and angles in the range 2.8887(15)-3.8357(16) Å and 47.51(3)-78.27(4)°, respectively.

Ruthenium(II) complexes of 1,3-thiazolidine-2-thione: Cytotoxicity against tumor cells and anti-Trypanosoma cruzi activity enhanced upon combination with benznidazole

“…However, two tautomeric forms can be found in aqueous and in organic solutions (i.e., 1,4-dioxane, CCl 4 , benzene, CHCl 3 , CH 2 Cl 2 , C 2 H 4 Cl 2s , EtOH, MeOH, CH 3 CN, DMF and DMSO) [31,32]. Given this promising outlook and considering the different coordination sites of the tzdtH [33][34][35], this work aimed to study the reactivity of this ligand with Ru(II) phosphine precursors. To the best of our knowledge, only three ruthenium organometallic compounds with anionic tzdt − are described in the literature, however no detailed structural as well as pharmacological evaluation were carried out [36,37].…”

A triclinic polymorph of 1,3-thiazolidine-2-thione (2-mercaptothiazoline)

“…In neutral and acid media, where (2) is the most stable form, usually the exocyclic S atom and the N atom are available as donor atoms (see, for example, Rajalingam et al, 2001;Bell et al, 2001;Popovic et al, 2002), whereas in alkaline media, it is the SÐCÐN component of the thiolate anion that is involved in coordination to metals (see, for example, Shi & Jiang, 2002;Du et al, 2002;Brandt & Sheldrick, 1998). An interesting complex with copper containing both forms (2) and (5) as donors has been observed by Raper et al (1998). Form (3) has been observed by Abram et al (1998) in an Au 3+ complex.…”
