Abstract :
A new family of three-legged piano stool structured organometallic compounds containing the η5-cyclopentadienylruthenium(II)/iron(II) fragments {M(η5-C5H5) (DPPE)}+, {Ru(η5-C5H5)(PPh3)2}+ and {Ru(η5-C5H5)(TMEDA)}+ with coordinated thiophene based chromophores, namely 5-(2-thiophen-2-yl-vinyl)-thiophene-2-carbonitrile (L1) and 5-[2-(5-Nitro-thiophen-2-yl)-vinyl]-thiophene-2-carbonitrile (L2) has been synthesized and fully characterized by 1H, 13C, 31P NMR, IR and UV–Vis spectroscopies. Also, electrochemical studies were carried out by cyclic voltammetry and all experimental data are interpreted and compared with related compounds under the scope of NLO properties. Compounds [Ru(η5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H3S))][CF3SO3] (1′Ru) [Fe(η5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H3S))] [PF6] (1Fe) and [Ru(η5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H2S)NO2)][CF3SO3] (4′Ru) were also crystallographically characterized.
