In the crystal structure of the title compound, C(10)H(8)N(4)·H(2)O, the organic mol-ecules are approximately planar [maximum deviation from the least-squares plane = 0.041 (2) Å]. Two mol-ecules are connected by two water mol-ecules via O-H⋯N hydrogen bonding into dimers, which are located around centres of inversion. In the crystal, mol-ecules are stacked in the a-axis direction, with mean distances between the π systems of 3.43 (1) and 3.46 (1) Å [centroid-centroid distances are 3.604 (2) and 3.591 (2) Å].
在标题化合物C(10)H(8)N(4)·H(2)O的晶体结构中，有机分子近似呈平面状[与最小二乘平面的最大偏差 = 0.041 (2) Å]。两个分子通过两个水分子经由O—H⋯N氢键连接形成二聚体，这些二聚体位于对称中心周围。在晶体中，分子沿a轴方向堆积，π体系之间的平均距离为3.43 (1)和3.46 (1) Å[质心间距为3.604 (2)和3.591 (2) Å]。
