Half sandwich iron S-bonded mono-thiocarbonate complexes: structure of CpFe(CO)2SCO2Et
摘要:
The synthesis and characterization of mononuclear iron complexes containing mono-thiocarbonate ligands are described. The new compounds of general formula CpFe(CO)(2)SCO2R [R = Et (1), iso-Bu (2), Ph (3), 4-C6H4NO2 (4), Me (5)] were prepared by reacting the iron sulfides (mu-S-x)[CpFe(CO)(2)](2) (x = 2, 3) with the corresponding chloroformates (ROCOCI). These new complexes have been characterized by elemental analyses and spectroscopic methods. The crystal structure of CpFe(CO)(2)SCO2Et, 1, has been determined by single crystal X-ray diffraction analysis. (C) 2003 Elsevier Ltd. All rights reserved.
