چکیده
In the bioactive title compound, [ZnBr(2)(C(9)H(13)NO)(2)], the Zn(II) atom is coordinated in a distorted tetra-hedral arrangement by two Br(-) anions and the O atoms of two zwitterionic organic ligands. The pyridinium rings are almost planar [maximum deviations = 0.004 (4) and 0.003 (4) Å]. The ethyl groups are approximately perpendicular to the corresponding pyridinium ring planes [N-C-C-C = 88.8 (4)° in each ligand]. The packing of the mol-ecules is controlled by π-π inter-actions, with centroid-centroid distances of 3.625 (3) and 3.711 (2) Å, forming chains approximately parallel to (102). The crystal studied was non-merohedrally twinned (twin relationship between the domains 1 0 0, 0 1 0, -0.4672 -0.1864 -1 and batch scale factor of 7.39%).

In the centrosymmetric title compound, [Zn(4)(C(9)H(6)NO)(6)(C(2)H(3)O(2))(2)]·2H(2)O, the Zn(II) atom that is bonded to one O atom of the acetate group is chelated by a quinolin-8-olate anion. This Zn atom is also bonded to the oxide O atoms of two other quinolin-8-olate anions, which themselves engage in chelation to the other Zn(II) atoms. The Zn(II) atom is five-coordinate in a square-pyram...
