Improved preparative routes for cyclopentadienyl (Cp) and substituted Cp (CO) 4 derivatives of niobium and tantalum and their precursors are described. New compounds are fully characterized by IR, NMR, and elemental analysis. The molecular structures of five compounds were determined:(vinylCp) Nb (CO) 4: triclinic, Pı̄, a= 6.770 (1) Å, b= 6.937 (1) Å, c= 12.706 (2) Å, α= 90.42 (1)°, β= 91.07 (1)°, γ= 105.560 (8)°, V= 574.71 (12) Å3, Z= 2, ...
