The title compound, [Co(C(10)H(9)NO(5)S)(H(2)O)(3)]·2H(2)O, is a cobalt-Schiff base complex derived from taurine. There are two complex mol-ecules and four solvent water mol-ecules in the asymmetric unit. The central Co atom is six coordinated by two O atoms and one N atom of the ligand and three O atoms of water mol-ecules, forming a slightly distorted octa-hedral geometry. The crystal structure is stabilized by several O-H⋯O hydrogen bonds.
