Abstract:
The reaction of the dithioether ligand, 2,3-bis(5-methyl-1,3,4-thiadiazole-2-thiomethyl) quinoxaline (L) with AgBF(4), leads to the formation of a novel complex {[AgL](BF(4))}(infinity) 1, which has been characterized by single-crystal X-ray diffraction analysis: monoclinic, space group C2/c, with a = 20.316( 7) angstrom, b = 12.401( 4) angstrom, c = 18.039( 6) angstrom, beta = 108.404(6)degrees and V = 4312( 3) angstrom(3). The crystal structure of the complex consists of 1D {[AgL](+)}(infinity) cation chain and BF(4)(-) anions. In 1, the coordination geometry of Ag(I) center can be best described as trigonal planar coordinated by three N from two distinct L ligands. The ligand is polydentate with one end adopting a bidentate conformation to chelate an AgI atom and the other end monodentate to bridge another AgI resulting in an infinite chain along b axis. There exist Ag center dot center dot center dot N weak coordination, pi - pi stacking and F center dot center dot center dot S weak interactions in the complex, and these weak interactions link the 1D complex into 3D supramolecular structure and further stabilize the crystal structure in the solid state.
