Tris{N-[(anthracen-9-yl)methyleneamino]thioureato}cobalt(III) tetrahydrate

Abstract

In the title complex, [Co(C16H12N3S)3]·4H2O, the central CoIII atom is in a distorted octa­hedral coordination environment. There are three N-[(anthracen-9-yl)­methyl­ene­amino]­thio­ureate ligands coordinated to the CoIII 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—H⋯O, O—H⋯O, O—H⋯N, and O—H⋯S hydrogen bonds.
