Abstract: In the title compound, [Pt₂Br₂(C₄H₆NO)₂(NH₃)₄](NO₃)₂, the intradimer Pt-Pt distance is 2.6476  (4)  Å. The axial Pt^III-Br bond distances at the N₄- and N₂O₂-coordinated sites are 2.5647  (9) and 2.5889  (8)  Å, respectively. The two Pt coordination planes are tilted by 18.1  (3)°, and the average torsional twist of the ligands about the Pt-Pt axis is estimated as 1.0°.
