Alkylation of [Fe(CO)2(S2C6H4)2]2- by Br(CH2)nBr (n = 1,3-6) or CICH2COCH2Cl yields [Fe(CO)2(C6H4S2-(CH2)n-S2C6H4)] and [Fe(CO)2(C6H4S2-CH2COCH2-S2C6H4)]. respectively. With long-chain dibromoalkanes (n = 7,8,12) the oligonuclear complexes [Fe(CO)2(C6H4S2 - (CH2)n - S2C6H4)]x also form; in these cases the mononuclear complexes can be obtained by dilution methods. Growing length of the bridge between the thioether donor atoms favours the loss of CO and formation of [Fe(CO)(C6H4S2-(CH2)3-S2C6Η4)]2 and [Fe(C6H4S2 - (CH2)n-S2C6H4)]x (n = 1,4-8,12). respectively; substitution rate of CO by PMe3 is increased as well. Hydrolysis of the Fe(CO)2 complexes by HCl gives the free tetradentate thioetherthiol ligands HSC6H4S - (CH2)n - S2C6H4SH.
