Cinnarizinium fumarate.

ABSTRACT: In the title salt {systematic name: 4-diphenyl-methyl-1-[(E)-3-phenyl-prop-2-en-1-yl]piperazin-1-ium (2Z)-3-carb-oxy-prop-2-enoate}, C26H29N2(+)·C4H3O4(-), the piperazine ring in the cation adopts a distorted chair conformation and contains a positively charged N atom with quaternary character. The dihedral angle between the mean planes of the phenyl rings of the diphenyl-methyl group is 74.2?(7)° and those between these rings and the phenyl ring of the 3-phenyl-prop-2-en-1-yl group are 12.7?(9) and 80.6?(8)°. In the crystal, N-H?O and O-H?O hydrogen bonds form chains along [001]. Weak C-H?O inter-actions connect parallel chains along [010], forming layers perpendicular to the a-axis direction.
