The coordination geometry around the manganese in decacarbonyldimanganese(0) is
- Trigonal bipyramidal
- Square pyramidal
- Square planar
- Octahedral
Answer
(4) Octahedral
Solution
[figure]
Mn2(CO)10: each Mn has 5 CO + 1 Mn–Mn bond ⇒ coordination number 6
∵ six ligands around each Mn are arranged octahedrally (axial CO trans to the Mn–Mn bond)
Answer: (4)
