Reactions of gold phosphane complexes [(AuX)(PR3)] (X = Cl, Br, I; R = organic moiety) with Se(SiMe3)2 lead to the formation of gold complexes with chalcogenide bridges. The reaction of the complex [Ph3PAuCl] and tBuSe(SiMe3) gives the cluster [Au5Se2(PPh3)4]Cl (1). The in situ preparation of the complex [(AuCl)2dpph] [dpph = Ph 2P(CH2)6PPh2] by reaction of dpph with [Me2SAuCl], and subsequent reaction with Se(SiMe 3)2, leads to the formation of [(Au3Se) 2(dpph)3]Cl2 (2). Reactions of the gold(I) complex [(AuCl)2dpppe] [dpppe = Ph2P(CH2) 5PPh2] with Se(SiMe3)2 and InCl 3 in different molar ratios lead to the formation of [Au 10Se4(dpppe)4]InCl5 (3) and [Au 4(SeInCl3)2(dpppe)2] (4). The reaction of [(AuCl)2dpph] with Te(SiMe3)2 and GaCl3 produces the isostructural cluster compound [Au 4(TeGaCl3)2(dpph)2] (5). From the reaction of Se(SiMe3)2 with [(AuCl)2dppe] [dppe = Ph2P(CH2)2PPh2] and InCl 3 [Au8Se4In(dppe)4](InCl 4)3 6 can be isolated. The structures of 1-6 were determined by X-ray diffraction.
