In the structure of the title salt, C6H16N2 (2+)·2NO3 (-), the cations are connected to the anions through bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds, generating corrugated layers parallel to the (100) plane. The organic cation is centrosymmetric and the diprotonated piperazine ring adopts a chair conformation, with the methyl groups occupying equatorial positions.
在标题盐C6H16N2(2+)·2NO3(-)的结构中，阳离子通过分叉的N-H⋯(O,O)和弱C-H⋯O氢键与阴离子相连，形成平行于(100)平面的波纹层。有机阳离子是中心对称的，双质子化的哌嗪环呈椅式构象，甲基占据赤道位置。
