Zusammenfassung

By employing silver salts with a weakly coordinating anion Ag[A] ([A]=[FAl{OC12F15}(3)], [Al{OC(CF3)(3)}(4)]), two phosphaalkynes could be coordinated side-on to a bare silver-(I) center to form the unprecedented homoleptic complexes [Ag(eta(2)-P equivalent to CtBu)(2)][FAl{OC12F15}(3)] (1) and [Ag(eta(2)-P equivalent to CtBu)(2)]-[Al{OC(CF3)(3)}(4)] (2). DFT calculations show that the ...
