Spectroscopic studies on organometallic compounds. Part XVI. Infrared spectra of organotin(carbonyl)iron complexes in the carbonyl stretching region
Abstract
An analysis has been made of the carbonyl stretching frequencies of complexes of formula [R2MFe(CO)4]2(M = Si, Ge, Sn, or Pb), [R2SnCl]2Fe(CO)4, (R3Sn)2Fe(CO)4, R4M3[Fe(CO)4]4(M = Sn or Pb), and M[Fe(CO)4]4(M = Ge, Sn, or Pb). Force constants have been calculated and their significance discussed.
