Darstellung und Kristallstrukturen von [Co6Se8(PPh3)6]+[CoCl3(THF)]¯ , [Co8Se8(PPh3)6][Co6Se8(PPh3)6] und [Co8Se8(PPh3)6]+[CoCl3(PPh3)]¯
Synthesis and crystal structures of [Co6Se8(PPh3)6]+[CoCl3(THF)]¯ , [Co8Se8(PPh3)6][Co6Se8(PPh3)6] und [Co8Se8(PPh3)6]+[CoCl3(PPh3)]¯
- (NBu4)[CoCl3(PPh3)] reacts with Se(SiMe3)2 to form the new clusters [Co8Se8(PPh3)6][CoCl3(PPh3)] (6) and [Co8Se8(PPh3)6][Co6Se8(PPh3)6] (7). The structures of 6 and 7 have been determ ined by X-ray diffraction. 6 and 7 crystallize in the space group P1̄ with two formula units per unit cell and with the following lattice constants at 180 K: 6: a = 1413.8(10), b - 2224.2(23), c = 2348.4(17) pm, α = 86.06(5), β = 86.58(5), γ = 76.11(5)°; 7: a = 1465.9(4), b = 1627.6(6), c = 2505.7(6) pm, α - 98.69(2), β = 96.23(2), γ = 113.06(2)°. The cluster structures of the [Co8Se8(PPh3)6]n (n = 0, 1 +) depend on the total number of electrons in the cluster units.
