要旨:
The asymmetric unit of the title compound, C18H16Br4N2O2, 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 intramolecular O—H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, molecules are linked by pairs of weak C—H⋯Br interactions into chains along [101], which include R22(8) ring motifs. These chains are further linked by C—H⋯O hydrogen bonds, forming a three-dimensional network.
