Complexes with dative bonds between d- and s-block metals: synthesis and structure of [(Cy3P)2Pt-Be(Cl)X] (X = Cl, Me).
A platinum-beryllium adduct (see structure) was prepared by the reaction of [Pt(PCy(3))(2)] and BeCl(2). Treatment with methyllithium resulted in ligand substitution at the beryllium center. Both complexes were structurally characterized and display unprecedented two-center two-electron bonds between a transition metal and beryllium.
