Bis[2-(2-pyridylmethyleneamino)benzenesulfonato-κ3N,N′,O]cobalt(II) dihydrate

Abstract

The title complex, [Co(C12H9N2O3S)2]·2H2O, has site symmetry 2 with the CoII cation located on a twofold rotation axis. Two tridentate 2-(2-pyridylmethyleneamino)benzenesulfonate (paba) ligands chelate to the CoII cation in a distorted octahedral geometry. The pyridine and benzene rings in the paba ligand are oriented at a dihedral angle of 42.86 (13)°. Intermolecular O—H...O and C—H...O hydrogen bonding is present in the crystal structure.
