(R)-1-Phenylethanaminium (S)-4-chloromandelate

Crystal 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 ...

(R)-1-Phenyl­ethanaminium (S)-4-chloro­mandelate

The absolute configuration of the title complex, C(8)H(12)N(+)·C(8)H(6)ClO(3) (-) or [R-C(6)H(5)C(H)CH(3)NH(3)][S-4-ClC(6)H(4)C(H)(OH)CO(2)], has been confirmed by the structure determination. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds form a two-dimensional network perpendicular to the c axis.

R 4 S Spiratory Complications from Tetraethylammonlumi

T HE tetraethylammonium ion has been used quite extensively since 1946, when Acheson and Moe1' 2 demonstrated its action as a blocking agent, effective at both sympathetic and parasympathetic ganglions. Earlier, Burn and Dalei and Hunt,4 had described the actions of certain quaternary ammonium bases which included the tetraethylammonium ion.* This drug has been used therapeutically with varying...

(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...
