Abstract
2,6-Diacetylpyridinebis(benzenesulfonylhydrazide) (2,6-DAPBSH) and its zinc(II) complex have been synthesized and characterized by X-ray crystallography. The ligand crystallizes in the monoclinic crystal system, space group Cc, with cell parameter = 16.808(2) Ǻ, b = 16.328(2) Ǻ, c = 8.2670(11) Ǻ, β = 91.869(9)°, while the zinc(II) complex crystallizes in the orthorhombic crystal system, space group Pbcn, with cell parameters a = 14.5927(3) Ǻ, b = 9.6502(2) Ǻ, c = 20.5610(5) Ǻ. The metal center is seven-coordinate, with an approximate pentagonal bipyramidal configuration of the chelating ligand and two apically coordinated DMSO molecules.
Graphical Abstract
X-ray crystallographic study on the [2,6-diacetylpyridine—bis(benzenesulfonylhydrazonato-κ5 N′N′′N′′′O′O′′)]bis(dimethyl sulfoxide-κO)zinc(II) (Fig. 1) shows that the complex is a seven-coordinate, with an approximate pentagonal bipyramidal configuration where the ligand coordinates to the zinc(II) ion as a pentadentate chelate via the pyridine nitrogen atom, the two azomethine nitrogen atoms and the two sulfonyl oxygen atoms.
