Abstract: The title compound, (CH₆N₃)₂[Pt(C₂O₄)₂] or (guanidinium)₂[Pt(ox)₂] (ox = oxalate), possesses an intriguing three-dimensional hydrogen-bonding network in the crystal structure, where extensive hydrogen bonds are formed between N-H(guanidinium) units and O atoms of oxalates [NO = 2.913  (5)-3.197  (5)  Å]. The [Pt(ox)₂]^2- anions stack weakly in a one-dimensional manner, with an intermolecular PtPt distance of 3.5876  (7)  Å. The Pt atom is located at an inversion centre.
