A new dinuclear silver(I)-saccharinato (sac) complex with acetonitrile (MeCN), [Ag-2(sac)(2)(MeCN)(2)](n) has been synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. The silver(I) ions are doubly bridged by two sac ligands, leading to a short argentophilic contact of 2.9074(3) angstrom. Each silver(I) ion exhibits a square-planar coordination geometry including the Ag-Ag bonds. The individual dimeric molecules are extended into a two-dimensional layered structure by weak Ag center dot center dot center dot Csac(eta(2)) interactions of ca. 3.2 angstrom. These interactions were discussed and compared with those found in the first silver(I)-sac complex [Ag(sac)](n). (C) 2008 Elsevier B.V. All rights reserved.
