Abstract

The first asymmetric bis(silyl) niobocene hydrides Cp 2Nb(SiHMe 2)H(SiXMe 2) (2: X = F (a), Cl (b), Br (c), I (d)), having interligand interactions Nb-H⋯ Si-X, were prepared by selective halogenation of the Si-H bond in Cp 2Nb(SiHMe 2) 2H. X-ray studies of 2b,c and a combined X-ray / neutron diffraction study of 2b establish a slightly stronger interaction of the niobium-bound hydride with the halosilyl ligand.
