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 [N...O = 2.913 (5)-3.197 (5) Å]. The [Pt(ox)2]2- anions stack weakly in a one-dimensional manner, with an intermolecular Pt...Pt distance of 3.5876 (7) Å. The Pt atom is located at an inversion centre.
