CpFe(CO)2TePh as a ligand for organometallic dihalides Fe(CO)4I2, (p-Cymene)RuI2, and Me5C5RhI2: Synthesis and molecular structures

Аннотация

CpFe(CO)₂TePh (I) can substitute one carbonyl group in Fe(CO)₄I₂ providing Fe(CO)₃I₂(μ-TePh)Fe(CO)₂Cp (II) or play role of ligand to monomeric fragments [(p-Cymene)RuI₂] and [Сp*RhI₂] (p-Cymene = (η⁶-1-isopropyl-4-methylbenzene); Сp* = η⁵-pentamethylcyclopentadienyl) provides the complexes (p-Cymene)RuI₂(μ-TePh)Fe(CO)₂Cp (III) and Cp*RhCl₂(μ-TePh)Fe(CO)₂Cp (IV), respectively. The single-crystal X-ray diffraction of complexes II–IV (CIF files CCDC nos. 1038124 (II), 1038127 (III), 1038125 (IV)) revealed the shortening of М–Те bonds and the presence of intramolecular I…Te contacts.
