✦ Synopsis
In the crystal structure of the title compound, C~10~H~24~N~4~O~2~
^2+^·2NO~3~
^−^ or H~4~dmaeoxd~2~ {H~2~dmaeoxd is N,N′-bis[2-(dimethylamino)ethyl]oxamide}, the diprotonated H~4~dmaeoxd dication occupies a special position on an inversion centre and exhibits a transoid conformation. The six non-H atoms of the oxamide group are almost exactly coplanar. Two symmetry-independent NH groups of the dication form hydrogen bonds with two O atoms belonging to one NO~3~
^−^ anion. Four independent C—H...O interactions link dications and anions into an infinite three-dimensional system.
