[S(Ph){Mn(CO)₂Cp}₂]⊕
Compound name(s): 
bis(dicarbonyl-η⁵₋cyclopentadienyl-manganese)-phenyl-sulfur(1+)
Central atom: 
Charge on formula unit (QN): 
1+
Compound type: 
Notes: 

The two metal groups each receive two electrons from the sulfur in σ bonds (the metal groups are Z). The sulfur receives two electrons from the two metal groups that act together as a set classified as an L π function. This takes the EN for sulfur to 8.
