MCQ
The structure of iron pentacarbonyl is:
  • A
    Square planar
  • Trigonal bipyramid
  • C
    Triangular
  • D
    None of these

Answer

Correct option: B.
Trigonal bipyramid
b
$Fe ( CO )_{5}$ adopts a trigonal bipyramidal structure with the Fe atom surrounded by five CO ligands: three in equatorial positions and two axially bound. The Fe-C-O linkages are each linear.
