title: Synthesis and crystal structure of bis(1-{[(quinolin-8-yl)imino]methyl}pyrene-κ2N,N')silver(I) tri-fluoro-methane-sulfonate.
abstract: The title compound, [Ag(qPyr)2]CF3SO3where qPyr = 1-(quinoline-2-yl-methyl-ene)amino-pyrene, C26H16N2, was synthesized from a reaction of silver tri-fluoro-methane-sulfonate and qPyr in di-chloro-methane-methanol mixed media. In this design, the qPyr ligand was chosen for its characteristic excitation and emission profiles, which could enable the tracking of the silver complex within biological targets. The AgIatom resides in a distorted tetra-hedral N4coordination sphere. Analysis of the packing pattern revealed significant intra- and inter-molecular π-π stacking inter-actions between the [Ag(qPyr)2]+cations. In addition, a weak C-H⋯O hydrogen bond consolidates the packing between cations and anions.
