Description / Table of Contents:
Ein neuer einkerniger Gold(I)-Komplex: Synthese und Röntgen-Struktur von [Au{P(C6H5)3}3][SiF5] · 1,5 CH2Cl2Tris(triphenylphosphan)gold(I)-pentafluorosilicat ([Au{P(C6H5)3}3][SiF5]) wurde dargestellt und durch eine Einkristallstrukturanalyse charakterisiert. Der Komplex kristallisiert triklin, Raumtemperatur P1 (Nr. 2) mit a = 14,634(2) Å, b = 17,180(2) Å, c = 22,212(3) Å, α = 86,48(1)°, β = 78,95(1)°, γ = 83,99(1)°, Z = 4. Die Goldatome sind von je drei Triphenylphosphin-Liganden koordiniert zum trigonal-planaren [Au{P(C6H5)3}3]+-Kation. Getrennt davon liegt das trigonal-bipyramidale Anion [SiF5]- vor. Zwischen den Fluor- und Goldatomen wird keine Wechselwirkung beobachtet.
Notes:
Tris(triphenylphosphine)gold(I)-pentafluorosilicate(IV) ([Au{P(C6H5)3}3][SiF5]) was prepared and the structure was determined by single crystal x-ray diffraction. The complex crystallizes in the triclinic space group P1 (No. 2). The lattice constants are a = 14.634(2) Å, b = 17.180(2) Å, c = 22.212(3) Å, α = 86.48(1)°, β = 78.95(1)°, γ = 83.99(1)°. Number of molecules per cell: Z = 4. The gold atoms are coordinated to three triphenylphosphine ligands to form the trigonal planar cation [Au{P(C6H5)3}3]+. Separated from the cation is the [SiF5]- anion which is regular trigonal bipyramidal coordinated. No interactions between the fluorine atoms and the gold atoms were observed.
