[Mn(OC₆F₅)(⭀NMe)₂]

Formula Unicode styled: 
[Mn(OC₆F₅)(⭀NMe)₂]
Compound name(s): 
tris(t-Butylimido)-(perfluorophenoxy)-manganese
Central atom: 
Manganese
Charge on formula unit (QN): 
0
Attached groups: 
OC₆F₅ (pentafluorophenoxy)
(⭀NMe)₂ (di(⭀NMe methylimino) Ⓢ)
Compound type: 
Molecular
Notes: 

At first sight the electron number (EN) for the metal is 20. However the three ⭀NBuᵗ groups are connected to the metal (approximately C3v through σ and π bonds but one of the π-set for the three ⭀NBuᵗ groups is A2. That has no match on the nine available orbitals in a C3v environment meaning the overall electron count for the metal is 18 rather than 20. I don't see an immediate reference for this so if my analysis is incorrect, or of you know of an appropriate reference, please let me know.
