摘要：
A triphosphine-stabilized Ag16Cu9 heterometallic alkynyl cluster complex was prepared by the reaction of polymeric silver(I) (4-tert-butylpheny1)acetylide with a copper(I) dpepp (dpepp = bis(2-(diphenylphosphino)ethyl)phenylphosphine) complex and characterized by X-ray crystallography. This Ag16Cu9 heterometallic alkynyl complex exhibits an unprecedented structural topology stabilized by three auxiliary triphosphine ligands. The (4-tert-butylphenypacetylide exhibits five types of asymmetric bonding modes, including mu-eta(1), mu-eta(1)(sigma):eta(2)(pi), mu(3)-eta(1), mu(3)-eta(1)(sigma):eta(1)(sigma):eta(2)(pi), and eta(1)-mu(4). This Ag16Cu9 complex exhibits visible to near-infrared luminescence in both fluid CH2Cl2 solution and the solid state.
