MOLECULAR-STRUCTURE AND SPECTRAL PROPERTIES OF BROMO(2-ACETYLPYRIDINEN-4-METHYLTHIOSEMICARBAZONATO)COPPER(II)

The anion (loss of 3N hydrogen) of 2-acetylpyridine 4N-methylthiosemic arbazone coordinates in a planar conformation to copper(II) through th e pyridyl nitrogen, azomethine nitrogen and thiolato sulphur atoms. Th e fourth coordination site is occupied by a bromo ligand and the compl ex is mononuclear and essentially planar. Bond distances and angles, a s well as solid state and solution spectral properties, are compared t o other recently reported copper(II) thiosemicarbazone complexes.
