Abstract

Two new saccharinato-silver(I) (sac) complexes, [Ag(sac)(ampy)] (1), and [Ag-2(sac)(2)(mu-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 P2(1)/c and triclinic space group P(1) over bar, respectively. The silver(I) ions in both complexes 1 and 2 exhibit a distorted T-shaped AgN3 coordination geometry. I consists of individual molecules connected into chains by N-H center dot center dot center dot 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 center dot center dot center dot Ag1 = 3.0199(4) angstrom and Ag2 center dot center dot center dot Ag2 = 2.9894(4) angstrom]. Symmetry equivalent dimers of 2 are connected by N-H center dot center dot center dot O hydrogen bonds into chains, which are further linked by aromatic pi(py)...pi(py) stacking interactions into sheets.
