| Abstract: | The crystal structure of the dimeric Ag maleonitriledithiolate complex, Ag2[S2C2(CN)2] [P(C6- H5)3]4 (1), has been performed. Complex 1 crystallizes in the space group P21/c with a = 12.2898(77), b = 23.8325(91), c = 23.1790(118) Å, β = 101.315(43)° and Z = 4. Refinement using 3253 reflections with Fo2>3σ(Fo2) yielded R = 0.0662, Rw= 0.0669. The most interesting aspect of the structure is the strong bridging interaction of the chelating maleonitriledithiolate ligand with the second Ag center, where a Ag-S distance of 2.478 Å is observed. The residual bonding capability of the sulfur atoms in the chelating anion [Ag(S2C2(CN)2)(PPh3)2]− for [Ag(PPh3)2]+ is demonstrated. |
