In analogy to that MCl2 reacts with Ph2PSiMe3 in the presence of PnPr3 to form the two multinuclear complexes [M4Cl4(PPh2)4(PnPr3)2] (M = Zn (3), Cd (4)). The structures were characterized by X-ray single crystal structure analysis (1: space group Pna21 (Nr. 33), Z = 4, a = 1 313.8(11) pm, b = 1 511.1(6) pm, c = 4 126.0(18) pm, 2: space group P-1 (Nr. 2), Z = 2, a = 1 559.0(4) pm, b = 1 885.9(7) pm, c = 2 112.4(8) pm, α = 104.93(3)°, β = 94.48(3)°, γ = 104.41(3)°; 3: space group C2/c (Nr. 15), Z = 4, a = 2 228.6(6) pm, b = 1 847.6(6) pm, c = 1 827.3(6) pm, β = 110.86(2); 4: space group C2/c (Nr. 15), Z = 4, a = 1 894.2(9) pm, b = 1 867.9(7) pm, c = 2 264.8(6) pm, β = 111.77(3)°). 3 and 4 may be considered as intermediates on the route towards polymeric [M(PPh2)2]n (M = Zn, Cd).

Analog dazu reagiert MCl2 mit Ph2PSiMe3 und PnPr3 zu den mehrkernigen Komplexen [M4Cl4(PPh2)4(PnPr3)2] (M = Zn 3), Cd (4)). Die Struktur der Komplexe konnte durch Kristallstrukturanalysen aufgeklärt werden (1: Raumgruppe Pna21 (Nr. 33), Z = 4, a = 1 313,8(11) pm, b = 1 511,1(6) pm, c = 4 126,0(18) pm, 2: Raumgruppe P1 (Nr. 2), Z = 2, a = 1 559,0(4) pm, b = 1 885,9(7) pm, c = 2 112,4(8) pm, α = 104,93(3)°, β = 94,48(3)°, γ = 104,41(3)°; 3: Raumgruppe C2/c (Nr. 15), Z = 4, a = 2 228,6(6) pm, b = 1 847,6(6) pm, c = 1 827,3(6) pm, β = 110,86(2); 4: Raumgruppe C2/c (Nr. 15), Z = 4, a = 1 894,2(9) pm, b = 1 867,9(7) pm, c = 2 264,8(6) pm, β = 111,77(3) 3 und 4 können als Vorstufen auf dem Weg zur Bildung von polymerem [M(PPh2)2]n (M = Zn, Cd) angesehen werden.

When PiPr(PtBu)2 and PiPrCl2 are allowed to react with [Fe2(CO)9] it is possible to isolate [Fe2(CO)3Cl2(PtBu)5] (4). The reactions of (PiPr)3 with [Co2(CO)8] and [Ni(CO)4] lead to the tetra- and pentanuclear clusters [Co4(CO)10(PiPr)3] (5), [Ni4(CO)10(PiPr)6] [2] and [Ni5(CO)10(PiPr)6] (6). Finally the reaction of [Ir(C8H12)Cl]2 with K2(PPh)4 leads to the complex [Ir4(C8H12)4Cl2(PPh)4] (7). The structures of 1-7 were obtained by X-ray single crystal structure analysis (1: space group P21/c (Nr. 14), Z = 8, a = 1 758.8(16) pm, b = 3 625.6(18) pm, c = 1 202.7(7) pm, β = 90.07(3)°; 2: space group P1 (Nr. 2), Z = 1, a = 880.0(2) pm, b = 932.3(3) pm, c = 1 073.7(2) pm, α = 79.07(2)°, β = 86.93(2)°, γ = 72.23(2)°; 3: space group Pbca (Nr. 61), Z = 8, a = 952.6(8) pm, b = 1 787.6(12) pm, c = 3 697.2(30) pm; 4: space group P21/n (Nr. 14), Z = 4, a = 968.0(4) pm, b = 3 362.5(15) pm, c = 1 051.6(3) pm, β = 109.71(2)°; 5: space group P21/n (Nr. 14), Z = 4, a = 1 040.7(5) pm, b = 1 686.0(5) pm, c = 1 567.7(9) pm, β = 93.88(4)°; 6: space group Pbca (Nr. 61), Z = 8, a = 1 904.1(8) pm, b = 1 959.9(8) pm, c = 2 309.7(9) pm. 7: space group P1 (Nr. 2), Z = 2, a = 1 374.4(7) pm, b = 1 476.0(8) pm, c = 1 653.2(9) pm, α = 83.87(4)°, β = 88.76(4)°, γ = 88.28(4)°).
    Notes: Die Cyclotriphosphane (PtBu)3 und (PiPr)3 reagieren mit [Fe2(CO)9] unter Bildung der Zweikernkomplexe [Fe2(CO)6(PR)6] (R = tBu: 1; iPr: 2). 2 entsteht auch bei der Reaktion von [Fe(CO)5] mit (PiPr)3 neben dem Komplex [Fe2(CO)4(PiPr)6] (3). Aus der Reaktion von PiPr(PtBu)2 und PiPrCl2 mit [Fe2(CO)9] kann weiterhin [Fe2(CO)3Cl2(PtBu)5] (4) isoliert werden. Die Umsetzungen von (PiPr)3 mit [Co2(CO)8] und [Ni(CO)4] führen zu den vier- und fünfkernigen Clustern [Co4(CO)10(PiPr)3] (5), [Ni4(CO)10(PiPr)6] [2] und [Ni5(CO)10(PiPr)6] (6). Weiterhin kann aus der Reaktion von [Ir(C8H12)Cl]2 mit K2(PPh)4 der Komplex [Ir4(C8H12)4Cl2(PPh)4] (7) erhalten werden.

    Description / Table of Contents: 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)°).
