在标题络合物[ZnBr2(C4H5N3O)2]中，中心金属离子与两个胞嘧啶分子中的两个溴离子和内环N原子配位，形成扭曲的四面体构型。其结构为[CdBr2(C4H5N3O)2][Muthiah等.(2001年)。Acta Cryst.E57，m558-m560]。存在两个配体间的N-H⋯-BR氢键，产生两个氢键环，稳定配位球。通过N-H⋯O和N-H⋯BR氢键和π-π堆积作用形成超分子链、片状和阶梯的复杂聚集体[质心-质心距离=3.616 (2) ä]。
In the title complex, [ZnBr2(C4H5N3O)2], the central metal ion is coordinated to two bromide ions and endocyclic N atoms of the two cytosine molecules leading to a distorted tetrahedral geometry. The structure is isotypic with [CdBr2(C4H5N3O)2] [Muthiah et al. (2001). Acta Cryst. E57, m558–m560]. There are two interligand N—H⋯Br hydrogen bonds, generating two hydrogen-bonded rings stabilizing the coordination sphere. The complex aggregates, forming supramolecular chains, sheets and staircases through N—H⋯O and N—H⋯Br hydrogen bonding and π–π stacking interactions [centroid–centroid distance = 3.616 (2) Å].
