Abstract

Interaction of Ag(CF₃CO₂) with bis(diphenylphosphino)amide (dppa) in THF gave a tetranuclear Ag₄-coplanar silver(I) complex [Ag₄(μ-dppa)₂(μ₄-O₂PPh₂)₂(μ-CF₃CO₂)₂] (1). The trinuclear trigonal-bipyramid copper(I) complex [Cu₃(μ₃-Cl)₂(μ-dppa)₃][CuCl₂] (2) was obtained from the reaction of [CuCl] powder with bis(diphenylphosphino)amide (dppa) in THF. Treatment of 2 with (Me₃Si)₂Se in THF afforded a μ₈-selenide-centered octanuclear copper(I) complex [Cu₈(μ₈-Se)(μ₄-Se)(μ₄-SeH)₃(μ-dppa)₄][(Ph₂PO)₂N] (3). The structures of 1-3 were determined by single-crystal X-ray diffraction analyses. Complex 1 comprises a rectangular Ag₄ array with each edge bridged with a pair of μ-dppa, μ₄-O₂PPh₂ and μ-CF₃CO₂ ligands that are approximately perpendicular to each other. Complex 2 contains a trigonal-bipyramid [Cu₃(μ₃-Cl)₂]⁺ core surrounded by three μ-dppa ligands. The cationic complex in 3 consists of four [Cu₂(μ-dppa)] fragments side-capped by one μ₄-Se and three μ₄-SeH ligands and center-connected by a μ₈-Se atom.
