[Au2μ-(CH2)2PPh2}2] with [Au2(μ-S2CPCy3)2](ClO4)2 leads to the heterobridged gold(I) complex [Au2μ-(CH2)2PPh2}(μ-S2CPCy3)](ClO4) 1. Complex 1 reacts with halogens via oxidative addition to give monocationic gold(II) derivatives [Au2μ-(CH2)2PPh2}(μ-S2CPCy3)X2](ClO4) (X = Cl 2, Br 3, or I 4) which undergo substitution reactions with silver salts to afford the first tricationic gold(II) complexes [Au2

[AuCl(CH2PPh3)] or [Ag(CH2PPh3)2]ClO4 with bis(diphenylphosphino)amine, bis(diphenylphosphino)methane, or bis(diphenylthiophosphoryl)amine leads to neutral complexes [X(Ph2PAuPPh2)2X][X = CH (1) or N (2)], [NPh2P(S)Au(S)PPh2}2N](3)[N(Ph2PAgPPh2)2N](4), or [NPh2P(S)Ag(S)PPh2}2N](5). Complexes (1), (2), and (4) react further with gold or silvercomplexes giving tetranuclear ring-system derivatives

Abstract A series of di- and polynuclear silver(I) complexes of stoichiometry [Ag(biisoq) 2 ] n X n and [AgX(biisoq)] (biisoq = 1,1′-biisoquinoline, X = CF 3 SO 3 , BF 4 ), or [(μ-biisoq) n (AgXL) 2 ] ( n = 1, 2; L = PPh 3 , PMePh 2 ; X = CF 3 SO 3 , ClO 4 ) have been prepared. During crystallization experiments to obtain single crystals the compounds can coordinate solvent or water giving the corresponding
