Abstract: | New Phosphido-bridged Multinuclear Complexes of Ag and Zn. The Crystal Structures of Ag3(PPh2)3(PnBu2tBu)3], Ag4(PPh2)4(PR3)4] (PR3 = PMenPr2, PnPr3), Ag4(PPh2)4(PEt3)4]n, Zn4(PPh2)4Cl4(PRR′2)2] (PRR′2 = PMenPr2, PnBu3, PEt2Ph), Zn4(PhPSiMe3)4Cl4(C4H8O)2] and Zn4(PtBu2)4Cl4] AgCl reacts with Ph2PSiMe3 in the presence of tertiary Phosphines (PnBu2tBu, PMenPr2, PnPr3 and PEt3) to form the multinuclear complexes Ag3(PPh2)3(PnBu2tBu)3] 1 , Ag4(PPh2)4(PR3)4] (PR3 = PMenPr2 2 , PnPr3 3 ) and Ag4(PPh2)4(PEt3)4]n 4 . In analogy to that ZnCl2 reacts with Ph2PSiMe3 and PRR′2 to form the multinuclear complexes Zn4(PPh2)4Cl4(PRR′2)2] (PRR′2 = PMenPr2 5 , PnBu3 6 , PEt2Ph 7 ). Further it was possible to obtain the compounds Zn4(PhPSiMe3)4Cl4(C4H8O)2] 8 and Zn4(PtBu2)4Cl4] 9 by reaction of ZnCl2 with PhP(SiMe3)2 and tBu2PSiMe3, respectively. The structures were characterized by X-ray single crystal structure analysis. Crystallographic data see “Inhaltsübersicht”. |
