Cobalt complexes supported by salicylichydrazono derivative ligands and various coordination solvents

We report the synthesis and molecular solid-state structures of five novel CoII and CoIII mononuclear complexes supported by the 2-salicyloylhydrazono-1,3-dithiolane (L1) and 2-salicyloylhydrazono-1,3-dithiane (L2) ligands. Moreover, one novel diamagnetic μ-oxo dinuclear CoIII complex [CoIII2(HL)4(μ-O)2] supported by the ligand L1 was stabilized and characterized. Crystal structure of the supporting ligand L2 was also determined.
