Bis(4-{2-[4-(diethylamino)phenyl]ethenyl}pyridine-κN)diiodidozinc

Abstract

In the title compound, [ZnI2(C17H20N2)2], the ZnII atom is four-coordinated by two I atoms and the N atoms of two pyridine rings belonging to different ligands in a distorted tetra­hedral geometry. The coordinating pyridine rings are oriented in an almost perpendicular fashion, making a dihedral angle of 83.7 (5)°.

Synthesis, characterization, and crystal structure analysis of Zn(II) and Cd(II) coordination compounds containing 4-((pyridin-4-ylmethylene)amino)phenol Schiff-base ligand

“…In this regard, Vittal and his coworkers report the crystal structure of [ZnBr2(4-styrylpyridine)2] in which Zn(II) is in perfect tetrahedral geometry and the dihedral angle between the two aromatic rings of 4-styrylpyridine ligand is similar to that for compound 1 [43]. In Hg(II) complexes containing substituted styrylpyridine ligand, the two aromatic rings of the corresponding ligand no longer show the large dihedral angle, but instead the two aromatic rings adopt a nearly coplanar geometry [44][45][46].…”
