Oxybispyridines, thiobispyridines and selenobispyridines

Molecular Strands and Related Properties of Silver(Ⅰ) Triflate with 3,3'-Oxybispyridine vs 3,3'-Thiobispyridine

“…3,3'-Py 2 O and 3,3'-Py 2 S were prepared according to the literature procedures. 27 Elemental analyses (C, H, N) were performed on crystalline samples by the Advanced Analytical Center at KIST with a Perkin-Elmer 2400 CHNS Analyzer. Thermal analyses were carried out under dinitrogen atmosphere at a scan rate of 10 o C/min with a Stanton Red Croft TG 100.…”

“…[23][24][25] 3,3'-Oxybispyridine (3,3'-Py 2 O) and 3,3'-thiobispyridine (3,3'-Py 2 S) as spacer ligands have similar angular and flexible components that possess non-rigid interannular dihedral angles between two pyridyl groups. [26][27][28] However, both anions exhibit delicate differences in the size, lone-pair delocalization, conformational energy barrier, and donating ability.…”

Crystal structure of tetrakis(μ2-acetato-κ2 O:O′)bis(2-((pyridin-4-ylmethyl)sulfanyl)pyridine-κN)dicopper(II), C30H32N4O8S2Cu2

“…2-((Pyridin-4-ylmethyl)sulfanyl)pyridine was synthesized according to a modi ed procedure in literature [1]. A mixture of 2-mercaptopyridine (0.56 g, 0.005 mol), 4-(chloromethyl)pyridine hydrochloride (0.82 g, 0.005 mol) and sodium hydroxide (0.6 g, 0.015 mol) was dissolved in methanol (20 mL) with stirring, which was re uxed for 4 h. Then the methanol was removed under vacuum, the product was extracted with CH 2 Cl 2 , and then the solvent was removed under vacuum.…”

A Topologically Novel Binuclear Silver Complex of Di-2-pyridyl Sulfide

“…1). Although many complexes of (1) have been described (Summers, 1987;Tresoldi et al, 1991), this is the first complex involving coordination of the S atom of the ligand, presumably as a consequence of the thiophilic nature of Ag I.…”
