Dibromidobis(1-ethyl-2,6-dimethylpyridinium-4-olate-κO)zinc(II)

Abstract

In the bioactive title compound, [ZnBr2(C9H13NO)2], the ZnII atom is coordinated in a distorted tetrahedral 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 molecules is controlled by π–π interactions, 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%).
