Bottom Line: The asymmetric unit of the title compound, 2C(8)H(6)N(2)·C(6)H(7)NO·2H(2)O, contains two quinoxaline mol-ecules, one mol-ecule of 3-amino-phenol and two water mol-ecules which are hydrogen bonded to form a two-dimensional polymeric structure.Each of the symmetry-independent quinoxaline mol-ecules forms separate stacks of different symmetry.In one set of stacks, the mol-ecules are related by a screw axis and are slightly tilted [dihedral angle = 7.12 (1)°].

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