Abstract
The title compound, tetraphenylborate salt of atropine (RS)-(8-Methyl-8-azabicyclo[3.2.1]oct-3-yl) 3-hydroxy-2-phenylpropanoate tetraphenylborate salt, was prepared by the reaction of (RS)-(8-Methyl-8-azabicyclo[3.2.1]oct-3-yl) 3-hydroxy-2-phenylpropanoate sulfate (2:1) salt with sodium tetraphenylborate in deionized water at ambient temperature through anion exchange reaction. Colorless crystals of the title compound suitable for X-ray structural analysis were obtained by slow evaporation from acetonitrile. The title compound crystallizes in the triclinic sp. gr. P (1) over bar with a = 9.7989(5)angstrom , b = 9.8203(5)angstrom , c = 18.6099(9)angstrom , alpha = 81.356(2)degrees, beta = 80.616(2)degrees, gamma = 67.704(2)degrees, V = 1627.05(14)angstrom(3), Z = 2.
