Bis(2,3-dimeth-oxy-10-oxostrychni-din-ium) phthalate nonahydrate.

ABSTRACT: The asymmetric unit of the title compound 2C23H27N2O4 (+)·C8H4O4 (2-)·9H2O, contains a cation, an anionon a twofold axis and four and half mol-ecules of water, one of which is located on the twofold axis. In the cation, both fused pyrrolidine rings exhibit twisted conformations, while the piperidine rings adopt screw-boat and boat conformations. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds. The brucinium cations form typical undulating head-to-tail ribbon structuresalong the a-axis direction, which associate with the carb-oxy phthalate and the water mol-ecules.
