Quinoxaline–3-amino­phenol–water (2/1/2)

The asymmetric unit of the title compound, 2C(8)H(6)N(2)·C(6)H(7)NO·2H(2)O, contains two quinoxaline mol­ecules, one mol­ecule of 3-amino­phenol and two water mol­ecules which are hydrogen bonded to form a two-dimensional polymeric structure. Each of the symmetry-independent quinoxaline mol­ecules forms separate stacks of different symmetry. In one set of stacks, the mol­ecules are related by a screw axis and are slightly tilted [dihedral angle = 7.12 (1)°]. In the second set of stacks, adjacent mol­ecules are parallel and related by an inversion center [inter­planar distances = 3.376 (4) and 3.473 (4) Å].
