Structures of 1-ferrocenyl-1-phenylethanol, ferrocenyl(diphenyl)methanol and ferrocene-1,1'-diylbis(diphenylmethanol)

Hydrogen bonding in α-ferrocenyl alcohols: structures of 1-ferrocenylethanol, 1-ferrocenyl-2-phenylethanol, 1-ferrocenyl-1-phenylpropan-1-ol, 1-ferrocenyl-1-phenyl-2-methylpropan-1-ol, 1-ferrocenyl-1-phenyl-2,2-dimethylpropan-1-ol, 1-ferrocenyl-1,2-diphenylethanol and diferrocenyl(phenyl)methanol

“…(Ferguson, Gallagher, Glidewell & Zakaria, 1993b). Although the closed (OH) 2 motif is unknown in simple unfunctionalized organic alcohols, CnHmOH, a_n.d has been described as 'highly improbable' , this motif is found not only in (If) but also in (2e), (2g) 1995): thus, although unknown in purely organic alcohols, this motif is actually rather common in aferrocenyl alcohols.…”

“…• -rr(CsHs) interactions [2a (Ferguson, Gallagher, Glidewell & Zakaria, 1993b)]. These examples, and others (Ferguson, Gallagher, Glidewell & Zakaria, 1993c;Glidewell, Ferguson, Lough & Zakaria, 1994), indicate that the hydrogen-bonding patterns in ferrocenyl alcohols are still very difficult to predict.…”

Intermolecular (pyrrole)N—H...π(pyrrole) interactions in bis(2-pyrrolyl)methylferrocene, an organometallic porphyrin precursor

“…In the structures of (I), (II) and (III), weak (pyrrole)N--H..-Tr(pyrrole) interactions dominate in the absence of stronger hydrogen-bond donors and acceptors. The hydrogen-bonding pattems in the crystal structures of a diverse range of ferrocene alcohol derivatives (Ferguson et al, 1993;Gallagher, Ferguson, Glidewell & Zakaria, 1994) have also been reported. Further studies are in progress on N--H-..Tr(pyrrole) interactions in related porphyrin precursors.…”

“…Rotational disorder is often observed in the unsubstituted C5 ring of ferrocene derivatives, e.g. 1-ferrocenyl-1-phenylethanol (Ferguson et al, 1993). The dihedral angle between the C5 planes are 1.1 (3) (A) and 3.6 (9) ° (B), with the rings staggered by 15.7(3) and 33.6(7) ° from an eclipsed [Fe(CsHs)(CI4HI3N2)] conformation in A and B (major isomer), respectively.…”

Intramolecular C—H...O and intermolecular N—H...O and C—H...O interactions inN-ferrocenoylglycine benzyl ester, an effective dihydrogen phosphate anion sensing agent

“…The range oOf Ccp---Ccp distances in (I) is 1.400 (4) In the asymmetric unit, molecules of (I) associate through intermolecular N H...O hydrogen bonds [N1...O1 i 2.811(3),~,; symmetry code: (i) 1 x, z-Y, ½ + z], forming a one-dimensional chain with graph set C(4) as depicted in Fig. 2 (details in Table 2 The hydrogen-bonding patterns in the crystal structures of a diverse range of ferrocene alcohol derivatives have been reported (Ferguson et al, 1993;Gallagher et al, 1994;Glidewell et al, 1997). dirner with graph set /P4(16) through C--H...O hydrogen bonds (Glidewell et al, 1997).…”
