Condensation of 2,6-diformyl-4-methylphenol with aliphatic diamines, NH2(CH2)nNH2 (n = 2–4) in the presence of [Ru(dmso)4Cl2] (dmso = dimethyl sulfoxide) resulted in acyclic dinuclear six-co-ordinate ruthenium(II) complexes [Ru2L(dmso)4Cl4]. The crystal structure of a representative complex was determined. However these reactions in the presence of PPh3 gave four-membered cyclometallated dinuclear complexes [Ru2L′(PPh3)4(CO)2Cl 2]. Compounds formed by condensation of 2,6-diformyl-4-methylphenol with aromatic monoamines reacted with [Ru(dmso)4Cl2]–PPh3 to give cyclometallated mononuclear ruthenium(II) complexes. The structure of a representative complex was determined. The facile formation of cyclometallated ruthenium complexes is rationalised. |
