Question

For each of the following pairs of complexes which one will have a higher carbonyl stretching frequency and explain your answer? (a) Ni(CO)4 and [V(CO)6]-

Answer 1

Answer:

In the IR, typical stretching frequencies are:

Uncoordinated or "free" CO: 2143 cm. -1

Terminal M-CO: 2125 to 1850 cm. -1

Doubly bridging (mu-2): 1850 to 1750 cm. -1

Triply bridging (mu-3): 1675 to 1600 cm. -1

Semibridging: somewhere between terminal and mu-2.
