Cyclic water pentamers in triclinic crystals of brucinium L-glycerate.

Abstract

Brucinium L-glycerate 4.75-hydrate, C23H27N2O4+.C3H5O4-.4.75H2O, was obtained by racemic resolution of DL-glyceric acid. This is the first report of triclinic crystals containing brucine. The water and L-glycerate anions form tapes built up of pentamers formed by water and carboxy O atoms, and this appears to be the reason for the low symmetry of the crystal.
