[P(NPrⁱ₂)(NPrⁱ₂)]⊕

Formula Unicode styled: 
[P(NPrⁱ₂)(NPrⁱ₂)]⊕
Compound name(s): 
bis(di-isopropylamino)phosphenium
bis(di-isopropylamino)phosphorus(1+)
Notes: 

Both groups planar but the A2 combination of the two out-of-plane N 2p orbitals is non-bonding with respect to phosphorus reducing the electron count to 8.
