Recebido em 12/9/08; aceito em 8/4/09; publicado na web em 26/8/09FeBr 2 has reacted with an equivalent of mnt 2-(mnt = cis-1,2-dicyanoethylene-1,2-dithiolate) and the α-diimine L (L = 1,10'-phenantroline, 2,2'-bipyridine) in THF solution, and followed by adding of t-butyl-isocyanide to give [Fe(mnt)(L)(t-BuNC) 2 ] neutral compound. The products were characterized by infrared, UV-visible and Mössbauer spectroscopy, besides thermogravimetric and conductivity data. The geometry in the equilibrium was calculated by the density functional theory and the electronic spectrum by the time-dependent. The experimental and theoretical results in good agreement have defined an octahedral geometry with two isocyanide neighbours. The π→π * intraligand electronic transition was not observed for cis-isomers in the near-IR spectral region.
Recebido em 19/11/99; aceito em 15/2/01 SYNTHESIS OF THE BINUCLEAR [Fe(CNBu t)(CO) 4 (HgSO 4)] ADDUCT. The binuclear [Fe(CNBu t)(CO) 4 (HgSO 4)] adduct was obtained in the reaction of HgSO 4 with [Fe(CNBu t)(CO) 4 ] in methanol. This adduct, without a similar in the homoleptic pentacarbonyliron, was characterized by analytical and spectroscopic data. Further Mössbauer and molar conductivity studies have confirmed it's adduct nature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
