Serendipitous syntheses and structures of [Cp2Nb(H)((SiMe2)2(mu-NR))].
The compound [Cp2Nb(SiMe2I)2H] reacts with H2NBut and HNEt2 to afford the unexpected imido-bridged 1,3-disilaniobocyclobutanes [Cp2Nb(H)((mu-SiR2)2NR)] (R = But (4), Et (5)) exhibiting surprising structural and spectral properties.
