Herein we report the syntheses, spectroscopic (FTIR, NMR and UV-Vis) and electrochemical (Cyclic Voltammetry) studies of the compounds with the general formulae [RuCpL2(CC{SC4H2}nNO2)] (L=PPh3; L2=DPPE; n=1,2). Overall data will be correlated in order to predict the corresponding first hyperpolarizabilities by comparison with those reported for parent benzenoid compounds.
