Abstract

In the title hydrated mol­ecular salt, C4H14N2O2+·C2O42−·H2O, 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.
