Melaminium formate

G. J. Perpétuo, M. A. Ribeiro and J. Janczak

Abstract: Crystals of a new melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium formate, C₃H₇N₆⁺·CHO₂^-, consist of singly protonated melaminium residues and formate anions. The components are linked by hydrogen bonds into a three-dimensional framework structure. The melaminium residues are interconnected by two pairs of N-HN hydrogen bonds into chains in the form of stacks, with a distance of 3.34 (1) Å between the triazine rings, clearly indicating - interactions. The chains of melaminium residues are interconnected via N-HO hydrogen bonds by the formate anions, forming a non-covalent superstructure.
