Description

A systematic series of η5-monocyclopentadienylruthenium(II) complexes with substituted thiophene nitrile ligands of general formula [Ru5-C5H5)(P_P)(NC{SC4H2}nNO2)][PF6] (P_P=dppe, (+)-diop; n=1-3) has been synthesized and characterized. Spectroscopic and electrochemical data were used in order to get an insight on the molecular nonlinear-optical properties of these complexes when compared to those found for the reported thiophene iron(II) and p-benzonitrile or 1,2-di-(2-thienyl)-ethene derived iron(II)/ruthenium(II) related complexes. The compound Ru5-C5H5)(dppe)(NC{SC4H2}2NO2)][PF6] was also characterized by X-ray diffraction. The solid state nonlinear optical properties of the chiral compounds were also evaluated by Kurtz powder technique with a Nd:YAG laser emitting at 1064 nm .
