Metal-nucleobase inter-action: bis[4-amino-pyrimidin-2(1H)-one-κN]dibromidozinc(II).

ABSTRACT: In the title complex, [ZnBr(2)(C(4)H(5)N(3)O)(2)], the central metal ion is coordinated to two bromide ions and endocyclic N atoms of the two cytosine mol-ecules leading to a distorted tetra-hedral geometry. The structure is isotypic with [CdBr(2)(C(4)H(5)N(3)O)(2)] [Muthiah et al. (2001). Acta Cryst. E57, m558-m560]. There are two inter-ligand N-H⋯Br hydrogen bonds, generating two hydrogen-bonded rings stabilizing the coordination sphere. The complex aggregates, forming supra-molecular chains, sheets and staircases through N-H⋯O and N-H⋯Br hydrogen bonding and π-π stacking inter-actions [centroid-centroid distance = 3.616 (2) Å].
