In the title compound, [Zn(2)Br(3)(CH(3)COO)(C(16)H(32)N(4))], one Zn(II) atom has a distorted square-planar coordination formed by the four macrocyclic N atoms with an acetate O atom in the apical position and the other Zn(II) atom has a tetra-hedral coordination environment formed by three Br atoms and one O acetate atom. The two Zn(II) atoms are linked by an acetate bridge. In the crystal, mol-ecules are linked into centrosymmetric dimers with graph-set motifs R(2) (2)(16) by an N-H⋯Br inter-action. The mol-ecular configuration is stabilized by an intra-molecular N-H⋯Br hydrogen bond.
在标题化合物[Zn₂Br₃(CH₃COO)(C₁₆H₃₂N₄)]中，一个Zn(II)原子具有由四个大环N原子形成的扭曲平面正方形配位，一个乙酸根O原子位于顶端位置；另一个Zn(II)原子具有由三个Br原子和一个乙酸根O原子形成的四面体配位环境。两个Zn(II)原子通过一个乙酸根桥相连。在晶体中，分子通过N—H⋯Br相互作用以R₂²(16)图式连接成中心对称二聚体。分子构型通过分子内N—H⋯Br氢键得以稳定。
