Neutron and X-ray Diffraction Studies and DFT Calculations of Asymmetric Bis(silyl) Niobocene Hydrides
The first asymmetric bis(silyl) niobocene hydrides Cp2Nb(SiHMe2)H(SiXMe2) (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 Cp2Nb(SiHMe2)2H. X-ray studies of 2b,c and a combined X-ray/neutron diffraction s...

Zusammenfassung: | The first asymmetric bis(silyl) niobocene hydrides Cp2Nb(SiHMe2)H(SiXMe2) (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 Cp2Nb(SiHMe2)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. |
