SYNTHESIS AND CRYSTAL STRUCTURE OF DI[(MU-ACETATO)(2-ACETYLPYRIDINE N-4-ETHYLTHIOSEMICARBAZONATO)ZINC(II)]

摘要

The reaction between zinc(II) acetate and the tridentate ligand 2-acetylpyridine N-4-ethylthio semicarbazone (H4EL) produces a dinuclear complex in which two deprotonated ligands are coordinated to two zinc(II) ions, one penta and the other hexacoordinate via the sulfur thiolato (on deprotonation) atom and the azomethine and pyridine nitrogen atoms. The coordination spheres of the metal atoms being completed by acetate oxygen atoms. One of the acetate ions chelates one zinc atom and bridges between the-two via a single oxygen, while in the other each oxygen coordinates to a different zinc atom. The results of elemental analysis and IR spectroscopy are included. (C) 1997 Elsevier Science Ltd. [References: 20]
