چکیده
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].

The title compound, [ZnBr(2)(C(4)H(5)N(3))(2)], is a mononuclear complex in which the Zn(II) ions have distorted tetra-hedral coordination geometry. The Zn(II) ion binds to two N atoms from two different 2-amino-pyrimidine ligands and two bromide ions. N-H⋯N hydrogen bonds link the mol-ecules to form a one-dimensional supra-molecular structure. The supra-molecular chains are parallel to each ot...

The title compound, [Cu(NCS)(2)(C(11)H(11)N(3)O)(2)], contains two independent Cu(II) atoms. Each Cu(II) atom, lying on an inversion center, is coordinated by two N atoms from two NCS(-) anions and two N atoms from two monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted square-planar geometry. Two S atoms from adjacent mol-ecules occupy the axial positions with lon...
