Morpholinium 2,4,6-trinitro-phenolate.

There are two independent formula units in the asymmetric unit of the title compound, C(4)H(10)NO(+)·C(6)H(2)N(3)O(7) (-). The morpholinium cations in both mol-ecules are puckered and adopt a chair conformation. Intermolecular N-H⋯O and C-H⋯O inter-actions generate rings of motifs R(2) (1)(5) and R(1) (2)(6). The supra-molecular aggregation is completed by the presence of two co-operative hydrogen-bonded networks of further N-H⋯O inter-actions, which generate an infinite one-dimensional chain along the base vector [100]. Two C-H⋯π interactions are also seen.
