Supramolecular structures of three configurational isomers of 1-phenylethanaminium malate(1-).
In rac-1-phenylethanaminium rac-malate(1ÿ), C8H12N C4H5O5 ÿ, (I), the anions are linked by two inter-anion OÐ H O hydrogen bonds into sheets generated by a glide plane and hence containing both enantiomers of the anion. The cations are linked to the anion sheets by three NÐH O hydrogen bonds, such that cations of R con®guration are bonded to one face of the sheet and cations of S con®guration a...
متن کاملAdsorption of sodium hexanoate on α-alumina.
Neutron reflection and adsorption isotherm measurements have been used to study the adsorption behaviour of hexanoic acid onto α-alumina surfaces. Importantly, the pH dependence of the behaviour has been characterised with a pronounced maximum in adsorption identified at a pH of approximately 5, close to the pKa of the acid. The adsorbed layer is identified as a bilayer, which is reasonable giv...
متن کاملCrystal structure of (R)-N-benzyl-1-phenylethanaminium (R)-4-chloromandelate
The absolute configuration of the title mol-ecular salt, C15H18N(+)·C8H6ClO3 (-), has been confirmed by resonant scattering. In the (R)-N-benzyl-1-phenyl-ethyl-ammonium cation, the phenyl rings are inclined to one another by 44.65 (7)°. In the crystal, the (R)-4-chloro-mandelate anions are linked via O-H⋯O hydrogen bonds and bridged by N-H⋯O hydrogen bonds involving the cations, forming chains ...
متن کامل(1S)-1-Phenylethanaminium 4-{[(1S,2S)-1-hydroxy-2,3-dihydro-1H,1'H-[2,2'-biinden]-2-yl]methyl}benzoate.
The title molecular salt, C(8)H(12)N(+)·C(26)H(21)O(3)(-), contains a dimeric indane pharmacophore that demonstrates potent anti-inflammatory activity. The indane group of the anion exhibits some disorder about the α-C atom, which appears common to many structures containing this group. A model to account for the slight disorder was attempted, but this was deemed unsuccessful because applying b...
متن کامل1 5 Se p 20 08 Hyperfine induced 1 s 2 s 1 S 0 → 1 s 2 1 S 0 M 1 transition of He - like ions
Hyperfine induced 1s2s S0 → 1s 2 S0 M1 transition probabilities of He-like ions have been calculated from relativistic configuration interaction wavefunctions including the frequency independent Breit interaction and QED effects. Present results for Eu and Gd are in good agreement with previous calculations [Phys. Rev. A 63, 054105 (2001)]. Electronic data are given in terms of a general scalin...
