Abstract Three new complexes [Cu2 (L) 4 (LH) 2](1),[Ni2 (L) 4 (EtOH) 2 (H2O) 2]. H2O. CHCl3 (2) and [Co2 (L) 4 (H2O) 2]. 3H2O (3), were obtained as coloured viscous liquids at room temperature (30 ºC) and in good yields from the reaction of sodium 2-hexyldecanoate (NaL) with the corresponding MCl2 (M= Cu, Ni or Co). The structural formulae of these complexes were indirectly deduced by a combination of analytical results and additionally ...
