Non-merohedrally twinned hexa-methyl-enetetra-mine-4-nitro-phenol-water (1/2/1), triclinic modification

The asymmetric unit of the title cocrystal, C(6)H(12)N(4)·2C(6)H(5)NO(3)·H(2)O, contains four formula units, which are linked by O-H⋯O and O-H⋯N hydrogen bonds into chains in the crystal. The crystal studied was a non-merohedral twin, with a minor twin component of 19%.
