Structure of bis(2-acetylpyridine 3-hexamethyleneiminylthiosemicarbazonato) palladium(II), a potential antitumor complex

The crystal structure of the potential antitumor complex bis(2-acetyppyridine 3-hexamethyleneiminylthiosemicarbazonato)palladium(II) has been solved. The palladium(II) atom is in a square planar environment surrounded by two cis nitrogen atoms and two cis sulfur atoms. The ligands are not equivalent...

Description
Summary:The crystal structure of the potential antitumor complex bis(2-acetyppyridine 3-hexamethyleneiminylthiosemicarbazonato)palladium(II) has been solved. The palladium(II) atom is in a square planar environment surrounded by two cis nitrogen atoms and two cis sulfur atoms. The ligands are not equivalent, one being tridentate with (N,N,S) donation, the other being monodentate using only the sulfur atom to coordinate to the metal. The tridentate ligand shows a Z, E, Z configuration while the monodentate ligand shows an E, E, Z. Intermolecular hydrogen bonds stabilize the structure, while the crystal packing is determined by Pd–C, Pd–π, C–H–π and π–π interactions.
