title: 6-Bromo-2-naphthol-piperazine (2/1).
abstract: In the title compound, 2C(10)H(7)BrO·C(4)H(10)N(2), the piperazine (pip) mol-ecule displays a chair conformation and is linked to two mol-ecules of 6-bromo-2-naphthol (bno) via O-H⋯N hydrogen bonds. Weak N-H⋯O hydrogen bonds from pip to bno mol-ecules result in chains propagating in [100]. The chains inter-act via C-H⋯π inter-actions.
