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

Abstract

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