In the title compound, C(3)H(7)N(6) (+)·C(7)H(5)O(5) (-)·2H(2)O, the melaminium and benzoate ions are approximately planar (r.m.s. deviation of the non-hydrogen atoms is 0.093 Å) and there is a strong C(2) (2)(8) hydrogen-bonding embrace between them. The centre of symmetry generates a second acid-base pair which is bound to the first by a C(2) (2)(8) (N-H⋯N) embrace common between melamine mol-ecules in similar compounds. Further extensive hydrogen bonding assembles the components into a three-dimensional hydrogen-bonded network.
在标题化合物C(3)H(7)N(6) (+)·C(7)H(5)O(5) (-)·2H(2)O中，三聚氰胺离子和苯甲酸根离子近似呈平面状（非氢原子的均方根偏差为0.093 Å），它们之间存在强烈的C(2) (2)(8)氢键结合。对称中心产生了第二对酸碱对，该对酸碱对通过类似化合物中三聚氰胺分子间共有的C(2) (2)(8)（N-H⋯N）结合与第一对相连。进一步广泛的氢键作用将各组分组装成三维氢键网络。
