Bis[2-(thiophen-2-yl)quinoxaline-κN 4]silver(I) tetrafluoridoborate
نویسنده
چکیده
In the title compound, [Ag(C12H8N2S)2]BF4, the two-coordinate Ag(I) ion lies on a crystallographic inversion center and is linearly bonded to the N-donor atoms of two separate quinoxaline ligands. The thio-phenyl ring of the ligand is nearly coplanar with the quinoxaline ring system [dihedral angle = 9.15 (13)°]. In the crystal, the complex mol-ecules pack in layers parallel to (-102) and form weak π-π ring stacking inter-actions [minimum ring centroid separation = 3.7054 (17) Å]. The tetra-fluoridoroborate anion is equally disordered about an inversion center.

The title compound, [Ag(2)(C(16)H(14)N(6))(2)](BF(4))(2), forms a centrosymmetric 22-membered metallamacrocycle via two Ag(I) ions bridging two 2,3-bis-(imidazol-1-ylmeth-yl)quinoxaline ligands. The Ag(I) ions are coordinated by two N donors of the imidazole groups, forming an approximately linear coordination geometry.
