Özet

Two new silver(I)-saccharinato (sac) complexes with ethylenediamine (en) and N,N-dimethylethylenediamine (dmen) were synthesized and characterized by elemental analysis, FT-IR spectroscopy; thermal analysis and single crystal X-ray diffraction. The [Ag-2(sac)(2)(en)(H2O)]n complex, 1, is a coordination polymer in which[Ag(sac)(2)(H2O)](-) and [Ag(en)(2)](+) ions are bridged by one of the sac ligands and Ag-Ag bonds [2.9920(3) angstrom], resulting in [Ag-2(sac)(2)(en)(H2O)] building blocks which are also linked into one-dimensional helical chains by bridging en ligands. Each silver(1) atom is three-coordinate with a distorted T-shaped coordination of AgN2O. The individual chains of 1 are further stacked by pi-pi; interactions, OW-H...O and N-H...O hydrogen to form a three-dimensional supramolecular framework. The [Ag-2(sac)2(en)2] complex, 2, has two molecules in its asymmetric unit, and each dieter is formed by bridging of two monomeric [Ag(sac)(dmen)] units by Ag-Ag bonds. The silver(I) atoms exhibit a distorted T-shaped coordination of AgN3 with an N-bonded sac and bidentate dmen ligands. The Ag...Ag separations in the pair of dimers are 3.2725(9) and 3.3127(9) angstrom. The dimeric molecules of 2 are connected to one-dimensional hydrogen bonded chains by N-H...O hydrogen bonds.
