In the title hydrated mol-ecular salt, C(4)H(14)N(2)O(2+)·C(2)O(4) (2-)·H(2)O, the oxalate dianion is almost planar (r.m.s. deviation = 0.020 Å). In the crystal, the components are linked by N-H⋯O(water), N-H⋯O(oxalate) O-H(ammonium)⋯O(oxalate), O-H(water)⋯O(oxalate) and O-H(water)⋯O(ammonium) hydrogen bonds, thereby forming a complex three-dimensional packing motif.
在标题水合分子盐C(4)H(14)N(2)O(2+)·C(2)O(4) (2-)·H(2)O中，草酸根二价阴离子几乎呈平面状（均方根偏差 = 0.020 Å）。在晶体中，各组分通过N-H⋯O（水）、N-H⋯O（草酸根）、O-H（铵）⋯O（草酸根）、O-H（水）⋯O（草酸根）和O-H（水）⋯O（铵）氢键相连，从而形成复杂的三维堆积模式。
