Complexes of the general formula Fe(CO)5-x (PR3)x are long known. The bimetallic Fe2(CO)9 reacts with triphenylphosphine in refluxing diethyl ether to afford a monosubstituted product Fe(CO)4(PPh3) with a trigonal bipyramid geometry. (a) Draw the possible isomers for the monosubstituted product Fe(CO)4(PPh3). (b) Determine the point group for each possible isomer above with reasons. (c) The monosubstituted product Fe(CO)4(PPh3) exhibits v(CO) absorptions at 2051, 1978, and 1945 cm¹ in hexane. Which isomer above is consistent with data? Support your decision by determining the number of IR-active CO stretching modes for these isomers. Complexes of the general formula Fe(CO)5-x (PR3)x are long known.
