Abstract:

In the title compound, C(4)H(8)N(2)O(3)·C(4)H(6)O(6), the amino acid mol-ecule exists as a zwitterion and the carb-oxy-lic acid in an un-ionized state. The tartaric acid mol-ecules are linked into layers parallel to the ab plane by O-H⋯O hydrogen bonds. The amino acid mol-ecules are also linked into layers parallel to the ab plane by N-H⋯O and C-H⋯O hydrogen bonds. The alternating tartaric acid and amino acid layers are linked into a three-dimensional framework by N-H⋯O and O-H⋯O hydrogen bonds.
