Formula Unicode styled:
[Sb(η²-Cp*){Cr(CO)₅}₂]
Compound name(s):
(η²-pentamethyl-cyclopentadienyl)-antimony-bis(pentacarbonyl-chromium)
Central atom:
Charge on formula unit (QN):
0
Compound type:
Notes:
The two metal groups each receive two electrons from the antimony in σ bonds (the metal groups are Z). The antimony 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 antimony to 8.
