Synthesis of hexametallic CH2{(η5-C5H4)Fe(CO)2SnPh2(η5-C5H5)Fe(CO)2}2
摘要:
The hexametallic complex CH2{(eta(5)-C5H4)Fe(CO)(2)SnPh2(eta(5)-C5H5)Fe(CO)(2)}(2) (3), has been synthesised and its crystal structure determined to exemplify Fe-Sn-Fe bond formation in related polymer systems. A potentially similar product was anticipated from the reaction of [(CH2{(eta(5)-C5H4)Fe(CO)(2)}(2)](2-) and Ph2SnCl2, however the cyclic complex {CH2(eta(5)-C5H5)Fe(CO)(2)}(2)SnPh2 (7), was isolated. The crystal structure of complex 7 shows that there is considerable strain in the ring containing the metal atoms. (C) 1999 Elsevier Science S.A. All rights reserved.
