In the crystal structure of the title compound, C4H8N2O4·C18H15OP, two triphenylphosphine oxide molecules and two dimethyl hydrazine-1,2-dicarboxylate molecules are connected via N—H⋯O hydrogen bonds of moderate strength and are related via a twofold rotational axis. Weak Car—H⋯ O contacts strengthen the crystal structure.
