| A new family of three-legged piano stool structured organometallic compounds containing the ¦Ç5-cyclopentadienylruthenium(II)/iron(II) fragments {M(¦Ç5-C5H5) (DPPE)}+, {Ru(¦Ç5-C5H5)(PPh3)2}+ and {Ru(¦Ç5-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¨CVis 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(¦Ç5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H3S))][CF3SO3] (1¡äRu) [Fe(¦Ç5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H3S))] [PF6] (1Fe) and [Ru(¦Ç5-C5H5)(DPPE)(NC(C4H2S)C(H)C(H)(C4H2S)NO2)][CF3SO3] (4¡äRu) were also crystallographically characterized. |
