Synthesis, characterization and fungitoxicities of metal chelates of a pentadentate N3S2 ligand
TL;DR: The Schiff base obtained by reaction of S-methyldithiocarbazate with 2,6-di-acetylpyridine behaves as a dinegatively charged pentadentate N 3 S 2 chelating agent producing stable crystalline complexes of the general formula, M(SNNNS) as discussed by the authors.

TL;DR: The nature of metal complexes of heterocyclic thiosemicarbazones reported in the literature through 1989 have been reviewed with an emphasis on variations in stoichiometry and stereochemistry as discussed by the authors.
Abstract: The nature of metal complexes of heterocyclic thiosemicarbazones reported in the literature through 1989 have been reviewed with an emphasis on variations in stoichiometry and stereochemistry. A brief introduction is followed by a survey of the biological activity of the uncomplexed thiosemicarbazones. Next is a section on the chemical nature of thiosemicarbazones including a discussion of preparative methods, modes of coordination and isomerism. This is followed by a discussion of structural information and biological activity of the iron(III), iron(II), copper(II), cobalt(III), cobalt(II) and nickel(II) complexes of heterocyclic thiosemicarbazones. Short sections on the biological activity of other chelating thiosemicarbazones and metal complexes are also included.

TL;DR: The Schiff base formed by condensation of 2,6-diacetylpyridine with S-benzyldithiocarbazate (H2SNNNS) behaves as a pentadentate ligand, forming a nickel(II) complex of empirical formula Ni(SNNns)·H2O that is high-spin with a room-temperature magnetic moment of 2.93 B as discussed by the authors.
