A Tetranuclear Iron Cluster Complex: [{Fe(CO)₃}₃{μ₃-CC[Fe(CO)₂(η⁵-C₅H₅)]C(CF₃)}]

Abstract

Undecacarbonyl[4(r/5)-cyclopentadienyl]-#3-(4,4,4-triduorobutaneheptayl)-tetrairon(3 Fe--Fe), [{Fe(CO)3 }3-5 {#3-CC[Fe(CO)2Cp]C(CF3)}] (Cp is 77-C5H5) contains a triangular {Fe(CO)3}3 core o[Fe--Fe distances 2.482 (1), 2.663 (1) and 2.693 (1) A] linked via an unusual C3CF3 bridging unit to an Fe(CO)2Cp group. CommentThe dinuclear complex [{Cp(CO)Fe}2{#-C2(CF3)2-SMe}2] (Cp is r/5-C5H5), (1), reacts with triiron dodecacarbonyl [Fe3(CO)12] to give #3-r/2-alkyne Acta Cr3"stallographica Section C
