Özet
Two new Ag(I)-saccharinate complexes, K[Ag(sac) 2] · H 2O (1) and [Ag(sac)(ina)] · 1.5 H 2O (2) (sac = saccharinate and ina = isonicotinamide), have been synthesized and characterized by elemental analyses, IR spectroscopy, thermal analysis and single crystal X-ray diffraction. The silver atoms adopt a linear AgN 2 geometry in each case defined by two sac ligands in 1, and one sac and one ina ligand in 2. In 1, the anionic complex units are linked into a two-dimensional array by two potassium atoms, forming an eight-membered bimetallic ring and a K 2O 10 potassium-oxygen cluster. Complex 2 shows rare (O-H) · Ag and (N-H) · Ag interactions. The molecules are connected by Ag · C sac (η 3) interactions involving the saccharinate-phenyl rings. © by Oldenbourg Wissenschaftsverlag, Müchen.
