C6Me4(C≡CH)2-1,2 [Ar(C≡CH)2] reacts with PPN[Au(acac)2] (acac = acetylacetonato, PPN = (Ph3P)2N) (2:1) or with [AuCl(SMe2)] and NEt3 (1:2:2) to give PPN[Au{C≡ CArC≡CH}2] (1) or [Au2{μ-Ar(C≡C) 2})]n (2), respectively. Dinuclear complexes of general formula [Au2L2{μ-Ar(C≡C)2}] can be obtained by reacting 2 with the appropriate ligand L (1:2) [L = tBuNC (3), PMe3 (4), PTo3 (5, To = C6H 4Me-4)] or L2 (1:1) (L2 = Ph 2P(CH2)nPPh2, n = 4 (6), 6 (7)]. The analogous complexes [(AuNHEt2)2{μ-Ar(C≡C) 2}] (8) and [{AuC(NHtBu)(NEt2)} 2{μ-Ar(C≡C)2}] (9) result from the reactions of Ar(C≡CH)2 with PPN[AuCl2] and NHEt2 (1: 2:4) or 3 with an excess of NHEt2, respectively, The reaction of 5 with AgClO4 (2:1) gives the heteropentanuclear "AgAu 4" complex [Ag{(AuPTo3)2{μ- Ar(C≡C)2}}2]ClO4 (10). The X-ray crystal structures of 3, 7, 9·1/3CHCl3, and 10·2CHCl 3 have been determined.
