Formula Unicode styled:
[W(OBuᵗ)₂(NO)(Cp*)]
Compound name(s):
bis(t-Butoxy)-(η-pentamethyl-cyclopentadienyl)-nitroso-tungsten
Central atom:
Charge on formula unit (QN):
0
Attached groups:
Compound type:
Notes:
Donation of π-electron density from the oxygen atoms of the two OBuᵗ groups is achieved as the oxygen p-orbitals are aligned with a metal π orbital that is not interacting significantly with the nitrosyl ligand. This is achieved as the two OBuᵗ groups interact as a X₂L set with the metal, bringing the electron number, EN, to 18. See, for instance:
