The title complex, [Co(C(12)H(9)N(2)O(3)S)(2)]·2H(2)O, has site symmetry 2 with the Co(II) cation located on a twofold rotation axis. Two tridentate 2-(2-pyridylmethyl-eneamino)benzene-sulfonate (paba) ligands chelate to the Co(II) cation in a distorted octa-hedral geometry. The pyridine and benzene rings in the paba ligand are oriented at a dihedral angle of 42.86 (13)°. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonding is present in the crystal structure.
