Abstract

CO)(p-CHCH&O, Et)(17) and [(C6H5)(CO) Fe] 2 (p-CO)(p-CHCH (C0zEt) CH (C0zEt) z)(16). Reductive dimerization of 2 gave the tetrairon carbene complex ([(C5H5)(CO) Fe] z (p-CO)(p- CHCHCOzEt)) z (25). The structure of 25 was determined by X-ray cr stallography, monoclinic space group R1/c, with unit cell constants a= 12.318 (2) A, b= 16.443 (2) 9: c= 17.679 (2) A, B= 105.20 (1) O, and Z= 4.
