Group 10 Metal Benzene-1,2-dithiolate Derivatives in the Synthesis of Coordination Polymers Containing Potassium Countercations

The use of theoretical calculations has allowed us to predict the coordination behavior of dithiolene [M­(SC6H4S)2]2– (M = Ni, Pd, Pt) entities, giving rise to the first organometallic polymers {[K2(μ-H2O)2]­[Ni­(SC6H4S)2]} n and {[K2(μ-H2O)2(thf)]2[K2(μ-H2O)2(thf)2]­[Pd3(SC6H4S)6]} n by one-pot reactions of the corresponding d10 metal salts, 1,2-benzenedithiolene, and KOH. The polymers are based on σ,π interactions between potassium atoms and [M­(SC6H4S)2]2– (M = Ni, Pd) entities. In contrast, only σ interactions are observed when the analogous platinum derivative is used instead, yielding the coordination polymer {[K2(μ-thf)2]­[Pt­(SC6H4S)2]} n .
