New manganese complexes with 2-salicyloylhydrazono-1,3-dithiolane ligand and various coordination solvents

Abstract

The new Mn ( HL ) 2 L 2 ′ complexes with 2-salicyloylhydrazono-1,3-dithiolane ligand (H 2L) have been obtained with good yields (≈85%) by reacting manganese (II) acetate tetrahydrate or manganese (II) acetylacetonate with 2-salicyloylhydrazono-1,3-dithiolane ligand in DMF, THF or Py (L′). These compounds have been fully characterized by spectroscopic methods and single crystal X-ray diffraction. In the solid state, supramolecular networks are described and discussed in terms of weak H-bonds and short contacts. The new monomeric complexes will be considered as candidates to obtain polynuclear complexes.
