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”.
Notes:
AgCl reagiert mit Ph2PSiMe3 in Gegenwart der tertiären Phosphane PnBu2tBu, PMenPr2, PnPr3 und PEt3 unter Bildung mehrkerniger Komplexe. Abhängig vom tertiären Phosphan erhält man dabei folgende Verbindungen: [Ag3(PPh2)3(PnBu2tBu)3] 1, [Ag4(PPh2)4(PR3)4] (PR3 = PMenPr2 2, PnPr3 3) und [Ag4(PPh2)4(PEt3)4]n 4. Analog hierzu reagiert ZnCl2 mit Ph2PSiMe3 und PRR′2 zu den Mehrkernkomplexen [Zn4(PPh2)4Cl4(PRR′2)2] (PRR′2 = PMenPr2 5, PnBu3 6, PEt2Ph 7). Ferner konnten durch Umsetzung von ZnCl2 mit PhP(SiMe3)2 bzw. tBu2PSiMe3 die Verbindungen [Zn4(PhPSiMe3)4Cl4(C4H8O)2] 8 und [Zn4(PtBu2)4Cl4] 9 erhalten werden. Die Strukturen von 1-9 konnten durch Kristallstrukturanalysen aufgeklärt werden.(1: Raumgruppe P1 (Nr. 2), a = 1 245,8(6) pm, b = 1 662,0(8) pm, c = 2 159,2(12) pm, α = 77,01(3)°, β = 81,59(3)°, γ = 69,07(3)°, 2: Raumgruppe P21/n (Nr. 14), a = 1 283,7(8) pm, b = 2 102,8(13) pm, c = 1 481,7(9) pm, β = 104,31(5)°, 3: Raumgruppe C2/c (Nr. 15), a = 2 925,4(12) pm, b = 1 297,0(6) pm, c = 2 426,5(9) pm, β = 100,00(3)°, 4: Raumgruppe P1 (Nr. 2), a = 1 046,0(5) pm, b = 1 086,1(7) pm, c = 1 733,0(12) pm, α = 71,76(5)°, β = 88,57(5)°, γ = 87,22(5)°, 5: Raumgruppe I2/a (Nr. 15), a = 2 435,2(9) pm, b = 1 908,3(8) pm, c = 3 534,3(16) pm, β = 97,04(3)°, 6: Raumgruppe C2/c (Nr. 15), a = 2 261,6(15) pm, b = 1 888,9(10) pm, c = 1 810,2(13) pm, β = 108,79(4)°, 7: Raumgruppe P1 (Nr. 2), a = 1 495,9(3) pm, b = 2 005,0(3) pm, c = 2 921,5(9) pm, α = 107,80(2)°, β = 92,36(2)°, γ = 103,99(1)°, 8: Raumgruppe P21/n (Nr. 14), a = 910,2(3) pm, b = 2 568,2(6) pm, c = 1 293,5(6) pm, β = 98,42(3)°, 9: Raumgruppe P21/n (Nr. 14), a = 1 227,3(6) pm, b = 1 205,3(9) pm, c = 1 584,5(7) pm, β = 109,32(3)°).
