Popis:	The reaction of 1,1′-bis[1–arylimino)ethyl]ferrocenes with cis-Pt(DMSO)2Cl2 in refluxing toluene and in the presence of NaOAc leads to meso and dl stereoisomers of biscyclometallated diplatinum complexes. Some individual stereoisomers were isolated successfully by column chromatography. The composition and the structure of the metallocycles were characterized by elemental analysis, IR and 1H NMR spectroscopy. A mechanism for the formation of stereoisomers in the cycloplatination reaction is suggested.
