Abstract: In the title complex, [Co(C₁₆H₁₂N₃S)₃]·4H₂O, the central Co^III atom is in a distorted octahedral coordination environment. There are three N-[(anthracen-9-yl)methyleneamino]thioureate ligands coordinated to the Co^III atom via three imine N and three thioamide S atoms. The Co-S and Co-N bond distances are in expected ranges [2.2194 (8)-2.2545 (8) and 1.926 (2)-1.985 (2)Å, respectively]. The endocyclic S-Co-N bond angles in the five-membered chelate rings range from 82.91 (7) to 85.33 (7)°. The structure contains four water molecules which are disordered over 12 sites and link the complex molecules into a three-dimensional network through N-HO, O-HO, O-HN, and O-HS hydrogen bonds.
