PROPARGYL ALCOHOL DERIVATIVES OF FE-2(CO)(6)(MU-EE')(E,E'=S,SE OR TE)- SYNTHESIS AND SPECTROSCOPIC CHARACTERIZATION OF (CO)(6)FE-2(MU-EC(H)=C(CH2OH)E')(E=SE OR TE E'=S, SE OR TE) - CRYSTAL-STRUCTURE OF (CO)(5)(PPH(3))FE-2(MU-SEC(CH2OH)=C(H)SE)

The propargyl alcohol derivatives (CO)(6)Fe-2{mu-EC(H)=C(CH2OH)E'} (E = Se or Te; E' = S, Se or Te) were obtained from the room-temperature reaction of Fe-2(CO)(6)(mu-EE') with propargyl alcohol and were charac terized by IR and H-1, C-13, Se-77 and Te-125 NMR spectroscopy. The st ructure of the PPh(3)-substituted derivative (CO)(5)(PPh(3))Fe-2{mu-Se C(CH2OH)=C(H)Se} was established by a single crystal X-ray diffraction study.
