Özet

Two new saccharinato-silver(I) (sac) complexes, [Ag(sac)(ampy)] (1), and [Ag2(sac)2(μ-aepy)2] (2), [ampy = 2-(aminomethyl)pyridine, aepy = 2-(2-aminoethyl)pyridine], have been prepared and characterized by elemental analysis, IR spectroscopy, thermal analysis and single crystal X-ray diffraction. Complexes 1 and 2 crystallize in the monoclinic space group P21/c and triclinic space group P1, respectively. The silver(I) ions in both complexes 1 and 2 exhibit a distorted T-shaped AgN3 coordination geometry. 1 consists of individual molecules connected into chains by N-H⋯O hydrogen bonds. There are two crystallographically distinct dimers in the unit cell of 2 and in each dimer, the aepy ligands act as a bridge between two silver(I) centers, resulting in short argentophilic contacts [Ag1⋯Ag1 = 3.0199(4) Å and Ag2⋯Ag2 = 2.9894(4) Å]. Symmetry equivalent dimers of 2 are connected by N-H⋯O hydrogen bonds into chains, which are further linked by aromatic π(py)⋯π(py) stacking interactions into sheets. © 2005 Verlag der Zeitschrift für Naturforschung.
