V. V. Chernyshev, S. Y. Efimov, K. A. Paseshnichenko and A. A. Shiryaev

Synopsis: The crystal packing motifs in two polymorphic modifications (monoclinic and ortho­rhom­bic) of the title salt are different, but the conformations of the anions are generally similar.

Formula: Two polymorphs of C8H12NO+·C7H10NO5-
