摘要：
The new dialkynyldigold(l) complexes [Ar(OCH(2)Cequivalent toCAu)(2)](n) {Ar = 1,4-C6H4(CMe2-4-C6H4)(2), 4,4'-C6H4C6H4 and 1,5-C10H6} react with diphosphines LL = Ph2P(CH2)(n)PPh2 (n = 1 to 6) and trans-Ph2PCH=CHPPh2 to give luminescent macrocyclic digold(I) or tetragold(I) complexes with bridging diphosphine and diacetylide ligands. The digold(I) complex [1,4-C6H4(CMe2-4C(6)H(4)OCH(2)Cequivalent toCAu)(2)(mu-LL)], with LL = trans-Ph2PCH=CHPPh2, forms a 28-membered ring, and the rings associate through aurophilic bonding in the solid state. In contrast, the tetragold(l) complex [4,4'-C6H4C6H4(OCH(2)Cequivalent toCAu)(2)(mu-LL)], with LL = Ph2PCH2PPh2, forms a more rigid 42-membered ring.
