The electrons are partially transferred from a d-orbital of the metal to anti-bonding molecular orbitals of CO (and its analogues). This electron-transfer (i) strengthens the metal–C bond and (ii) weakens the C–O bond. The strengthening of the M–CO bond is reflected in increases of the vibrational frequencies for the M–C bond (often outside of the range for the usual IR spectrophotometers). Furthermore, the M–CO bond length is shortened. The weakening of the … Web5 mrt. 2015 · which states that the sum of the metal valence electrons and the bonding electrons contributed by the ligands equals a total of 18 valence electrons. Langmuir then illustrated how the metal carbonyl compounds Ni(CO) 4, Fe(CO) 5, and Mo(CO) 6 all exhibited structures consistent with those predicted by this relationship [3, 4].
