A series of alkynylgold(I) bis(diphenylphosphino)alkyl- and aryl-amine complexes, [{Ph₂PN(R)PPh₂}Au₂(C{triple bond, long}CR′)₂] [R = ⁿPr, R′ = Ph (1), C₆H₄OMe-p (2), C₆H₄Me-p (3), C₆H₄Cl-p (4); R = C₆H₄OMe-p, R′ = Ph (5)], has been synthesized. The X-ray crystal structures of 1 and 2 revealed the presence of short intramolecular Au?Au contacts with the distances of 2.8404(8) and 3.0708(7) ?. The luminescence behavior of the complexes were studied.
