Unidentate diphosphine complexes. Crystal structure and molecular geometry of Fe(CO)4(η1-PPh2CH2CH 2PPh2)

The unidentate diphosphine complexes Fe(CO)4(η1-PPh2CH2CH 2PPh2) and trans-Fe(Co)3(η1-PPh2CH2CH 2PPh2)2 have been prepared by base-promoted addition of PPh2H to Fe(CO)4(PPh2CH=CH2) and trans-Fe(CO)3(PPh2CH=CH2)2, respectively. The crystal structure and molecular geometry of Fe-(CO)4(η1-PPh2CH2CH 2PPh2) have been determined by X-ray diffraction techniques. The compound crystallizes in the monoclinic space group P21/c with a = 8.518 (3) A?, b = 21.897 (6) A?, c = 14.341 (3) A?, and β = 93.74 (3)°. The geometry about iron is trigonal bipyramidal with one end of the diphosphine bonded axially. 31P{1H} NMR shows that phosphorus-phosphorus coupling through the metal in trans-Fe-(CO)3(η1-PPh2CH2CH 2PPh2)2 is relatively small (30.4 Hz).
