The asymmetric unit of the title compound, C(18)H(16)Br(4)N(2)O(2), comprises half the molecule, which is located adjacent to an inversion centre at the mid-point of the central C-C bond of the butane-1,4-diamine segment. There are two intra-molecular O-H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of weak C-H⋯Br inter-actions into chains along [101], which include R(2) (2)(8) ring motifs. These chains are further linked by C-H⋯O hydrogen bonds, forming a three-dimensional network.
标题化合物C(18)H(16)Br(4)N(2)O(2)的不对称单元包含半个分子，该分子位于丁烷-1,4-二胺片段中心C-C键中点的一个对称中心附近。存在两个形成S(6)环模式的分子内O-H⋯N氢键。在晶体中，分子通过成对的弱C-H⋯Br相互作用沿[101]方向连接成链，其中包含R(2) (2)(8)环模式。这些链通过C-H⋯O氢键进一步连接，形成三维网络。
