In the title compound, C(10)H(22)N(2) (2+)·2Br(-), a precursor in the synthesis of organocatalysts, the bipiperidinium ion is located on a twofold rotation axis which passes through the mid-point of the central C-C bond. The piperidinium ring adopts a chair conformation. In the crystal, the cations are linked together by Br(-) ions through N-H⋯Br hydrogen bonds, forming layers parallel to the ab plane.
在标题化合物C(10)H(22)N(2)(2+)·2Br(-)（一种有机催化剂合成中的前体）中，双哌啶离子位于一个通过中心C-C键中点的二重旋转轴上。哌啶环呈椅式构象。在晶体中，阳离子通过N-H⋯Br氢键被Br(-)离子连接在一起，形成平行于ab平面的层。
