In the title ferrocene derivative, [Fe(C5H5)(C9H8NO)], the dihedral angle between the ene-nitrile group and the substituted cyclo-penta-dienyl ring is 71.2 (1)°. The cyclopentadienyl rings of the ferrocene moiety are arranged in an eclipsed conformation. The hy-droxy group, and the corresponding methine H atom, are disordered over two sets of sites with site-occupancy factors of 0.744 (4) and 0...

The first examples of redox-active ferrocene-functionalised neutral [2]rotaxanes have been synthesised via chloride anion templation. (1)H NMR spectroscopic titrations reveal that these [2]rotaxane host systems recognize chloride selectively over other halides and oxoanions in highly-competitive aqueous media. By replacing the hydrogen bonding prototriazole units of the rotaxane axle component ...

Deformation twinning, which is a type of plastic deformation, has been particularly investigated in metal materials. However, only a few examples are found in organic solids. We observed mechanical twinning deformation on a simple ferrocene crystal, which is considered the most representative organometallic compound, and evaluated the crystal structures under the twinning state and the shear de...

The bioorganometallic III containing trimethylene chain between ferrocene and resveratrol (3,5,4'-trihydroxystilbene, RSV) moieties connected via ester bond has been synthesized. The novel bioconjugate was characterized using IR and NMR (1H, 13C, COSY, NOESY, HMBC) spectroscopy, ESI-MS and HRMS. The RSV and ferrocene-RSV conjugate III were screened in vitro for their inhibitory effects against ...

Linear arrays of 3 nm wide Fe stripes with 15 nm spacing are fabricated by self-assembly. They are formed by photolysis of ferrocene that is selectively adsorbed between CaF2 stripes. An ultraviolet nitrogen laser removes the organic ligands from ferrocene. Arrays of CaF2 stripes serve as masks, which are self-assembled on a stepped Si~111! surface. Scanning tunneling microscopy is used to inve...

The structure of the title salt, (C5H7N2)[Fe(C6H4O2)(C6H5O2)], consists of 3-amino-pyridinium cations and 1'-carb-oxy-ferrocene-1-carboxyl-ate monoanions. The ferrocenyl moiety of the anion adopts a typical sandwich structure, with Fe-C distances in the range 2.0270 (15)-2.0568 (17) Å. The anion possesses an eclipsed conformation, with the torsion angle φ (Csubst-Cpcent-Cpcent- Csubst) equal to...

The reaction of 2,2′-diiodo-1,1′-biphenyl (1a) with ethynyl ferrocene (2) gave trace amounts the expected 2,2′-bis(ferrocenylethynyl)-1,1′-biphenyl (3) together 9-(ferrocenyl(ferrocenylethynyl)methylene)-9H-fluorene (4), formed via a cyclization process during Sonogashira cross-coupling reaction, as major product. In contrast, similar 2,2′-diiodo-1,1′-diphenyl ether analogue 2 anticipated 2,2′-...

An efficient synthesis of 1,1?,2,2?-tetraiodoferrocene is described that uses 1,1?,2,2?-tetrakis(tri-n-butylstannyl)ferrocene as a key intermediate in its synthesis. In an attempt to examine the stepwise mechanism, reaction tetratin-substituted ferrocene with iodine was monitored by 1H NMR and series coexisting compounds such 1,1?-bis(tri-n-butylstannyl)-2,2?-diodoferrocene were observed. The c...
