[Mn(⭀NBuᵗ)₃(NH₂Buᵗ)]⊕

Formula Unicode styled:

Compound name(s):

t-Butylamine-tris(t-butylimido)-manganese(1+)

Central atom:

Manganese

Charge on formula unit (QN):

Attached groups:

(⭀NBuᵗ)₃ (tri(⭀NBuᵗ t-butylimino) Ⓢ)

NH₂Buᵗ (t-butylamine)

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 C_3v 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 C_3v 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.
