In the title co-crystal, C(12)H(12)N(6)O(4)·C(14)H(16)N(4)O(2)S, both mol-ecules are essentially planar [maximum deviations = 0.129 (1) and 0.097 (1) Å, respectively]. The tricyclic and Schiff base mol-ecules are alternately stacked along the a axis and are linked by π-π inter-actions with centroid-centroid distances of 3.5170 (16) and 3.6576 (17) Å. An intra-molecular C-H⋯O hydrogen bond and a C-H⋯S contact occur in the Schiff base molecule. In the crystal, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds lead to the formation of a three-dimensional network.
在标题共晶体C(12)H(12)N(6)O(4)·C(14)H(16)N(4)O(2)S中,两个分子基本呈平面状[最大偏差分别为0.129 (1) 和0.097 (1) Å]。三环分子和席夫碱分子沿a轴交替堆积,并通过π-π相互作用相连,质心间距为3.5170 (16) 和3.6576 (17) Å。席夫碱分子中存在分子内C-H⋯O氢键和C-H⋯S接触。在晶体中,N-H⋯O、N-H⋯N和C-H⋯O氢键导致形成三维网络。
