[AsCl{Cr(CO)₅}₂]

Formula Unicode styled: 
[AsCl{Cr(CO)₅}₂]
Compound name(s): 
Chloro-bis(pentacarbonyl-chromium)-arsenic
Central atom: 
Arsenic
Charge on formula unit (QN): 
0
Attached groups: 
Cl (chloro)
Cr group (Z type)
Compound type: 
Molecular
Notes: 

The two metal groups each receive two electrons from the arsenic in σ bonds (the metal groups are Z). In addition the arsenic receives two electrons from the two metal groups which act together as a set classifed as a L π function. This last L function takes the electron count from 6 to 8.
