Melaminium hydrogen malonate.


ABSTRACT: The melaminium (2,4,6-triamino-1,3,5-triazin-1-ium) cation in the title compound, C(3)H(7)N(6) (+)·C(3)H(3)O(4) (-), is essentially planar, with a r.m.s. deviation of the non-H atoms of 0.0085 Å. Extensive hydrogen bonding of the types N-H⋯N and N-H⋯O between cations and cations and between cations and hydrogen malonate (2-carb-oxy-ethano-ate) anions leads to the formation of supra-molecular layers parallel to (1-2-1). An intra-molecular O-H⋯O hydrogen bond in the single deprotonated malonate anion also occurs.
