Notes. Synthesis and structural studies of some 1,1′-dichloroferrocene derivatives of platinum(II). Crystal and molecular structure of 2,2-µ-[(1–2,5–6-η-cis,cis-cyclo-octa-1,5-diene)platinio]-bis(1,1′-dichloroferrocene)

Abstract

The synthesis and characterisation of complexes of platinum, of the general formula [Pt(cod){Fe(C₅H₄Cl)(C₅H₃Cl)}L][cod =cis,cis-cyclo-octa-1,5-diene; L = Cl, Br, I, CH₃, CH₂Ph, or Fe(C₅H₄Cl)(C₅H₃Cl)], are reported. A single-crystal X-ray structure determination of [Pt(cod){Fe(C₅H₄Cl)(C₅H₃Cl)}₂](R= 0.0485 for 2 553 independent reflections) showed a DL arrangement of the ferrocenyl groups, with a single crystal consisting of molecules of one enantiomer.
