Abstract
Bis[1,2-bis(diethylphosphino)ethane-P,P']-hydrido(dinitrogen-N)iron(II) tetraphenylborate, [FeH(N 2 )(C 10 H 24 P 2 ) 2 ](C 24 H 20 B), M r =816.6, monoclinic, P2 1 /n, a=16.493 (3), b=13.691 (4), c=21.422 (8) A, β=111.20 (2) o , V=4509.8 A 3 , Z=4, D x =1.203 Mg m -3 , λ(Mo Kα)=0.7107 A, μ=0.503 mm -1 , F(000)=1752, T=293 K, R=0.0651 for 5651 independent observed reflections. The title compound was prepared in 86% yield from [FeHCl{(h 5 C 2 ) 2 PCH 2 CH 2 P(C 2 H 5 ) 2 } 2 ] and NaBPh 4 in methanol under an atmosphere of nitrogen. the molecule consists of hydride trans to end-bound molecular nitrogen and two biphosphine ligands in a pseudo-octahedral arrangement about the iron centre
