Synthesis and Spectroscopic Characterization of the Four Complete Series [(C5XnH5‐n)Fe(CO)2R] (X= Cl, Br; R= Me, Ph; n= 1–5). Molecular and Crystal Structures of [(C5X5)Fe(CO)2R

Abstract

AbstractThe complete series of chloro‐ and bromo‐cyclopentadienyl carbonyl complexes [(C5XnH5‐n)Fe(CO)2R] (n=1–5, R=Me, Ph) could be prepared from the unsubstituted parent compounds via a sequence of lithiations and electrophilic halogenations. All four pentahaloyclopentadienyl complexes were studied by X‐ray diffraction and show an interplay of weak intermolecular X…X, X…O and X…H interactions.
