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

Metallosupramolecular silver complexes of bis- and tetrakis-(2-pyridylsulfanylmethyl)benzenes

“…Such a substructure is also present in the silver nitrate complex of di-2-pyridyl sulfide. 12 Fused to this macrocycle is a twenty-membered centrosymmetric dinuclear ring. Again, the ring is formed by coordination of a pyridine nitrogen and a sulfur atom to each of two silver atoms.…”

“…11 Furthermore, we have recently shown that reaction of silver nitrate with di-2-pyridyl sulfide, a ligand that normally acts as a N,N-bidentate chelating ligand, results in the formation of a novel binuclear complex in which the ligand co-ordinates in an N,N,S-tridentate bridging mode to form a structure with the same topology as those of the well studied organic photodimers of anthracene. 12 The study of such assembly processes can provide useful information for use in the rapidly expanding area of crystal engineering. 13 We now report the preparation of four new bridging ligands that contain 2-pyridylsulfanyl groups attached to xylylene cores, and the synthesis and crystal structures of their respective complexes with silver() nitrate.…”

(Di-2-pyridyl sulfide-κ2N,N′)diiodidozinc(II)

“…When dps is connected to the metal atom as a chelate ligand, a six-membered ring in boat conformation is formed, differently from its rigid analogues 2,2′-bipyridine that generates a pentacyclic chelate in a planar arragement. In addition, in some cases dps can act as tridentate ligand in a N,N,S-coordination mode involving metal-sulfur interactions (Anderson & Steel, 1998). …”

Extension of a π-stacked N2S ligand to form bi- and tri-nuclear silver(i) complexes

“…Reaction of a related ligand di-2-pyridyl sulfide with Ag(I) produces a binuclear dimer containing two ligands. 5 This work would suggest 1 may not be ideally suited to forming mononuclear Ag(I) complexes. Electrospray mass spectrometry under normal operating conditions showed parent ions with appropriate isotope patterns for {[Ag 2 (1) 2 ]PF 6 } + at m/z 790.8 and [Ag 2 (1) 2 ] 2+ at m/z 323.5.…”
