Chloro[diferrocenyl(phenyl)phosphine]gold(I)

[AuCl{P(C6H5)(C10H9Fe)2}], Mr=710.5, monoclinic, P21/n, a=10.205(2), b=18.014(4), c=12.680(3) A, β=98.29(2)0, V=2306.5 A3, Z=4, Dx=2.04 Mg m-3, λ(Mo Kα)=0.71069 A, μ=7.8 mm-1, F(000)=1368, T=293 K. The structure was refined to R 0.035 for 3523 unique observed reflections. The coordination geometry at the Au atom is linear, with Au-Cl 2.289(2), Au-P 2.234(2) A, Cl-Au-P 176.1(1)0. There are no unusually short intermolecular contacts. The Fe-C distances lie in the range 2.025(8)-2.058(8) A, mean 2.041(8) A. The C5H4 rings of the ferrocence moieties are approximately eclipsed (rotated by 12, 140, respectively). (orig.)
