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.
Synthesis and characterization of a three-legged piano stool structured organometallic family possessing coordinated chromophores derived from 1,2-di-(2-thienyl)-ethene. Spectroscopic and electrochemical studies are compared with other related compounds and discussed under the scope of potential nonlinear optical properties.Figure optionsDownload as PowerPoint slide
