Crystal structure of Ag2(μ-SCN)2(NH3)4.

ABSTRACT: Di-μ-thio-cyanato-bis-[diamminesilver(I)], [Ag2(μ-SCN)2(NH3)4], was synthesized by the reaction of AgSCN with anhydrous liquid ammonia. In the binuclear mol-ecule, the Ag(I) atom is coordinated by two ammine ligands and the S atom of one thio-cyanate ligand. Two of these [Ag(SCN)(NH3)2] units are bridged by the S atoms of the thio-cyanate anions at longer distances, leading to a dimer with point group symmetry C 2. The distance between the Ag(I) atoms in the dimer is at 3.0927 (6) Å within the range of argentophilic inter-actions. The crystal structure displays N-H⋯N and N-H⋯S hydrogen-bonding inter-actions that build up a three-dimensional network.
