Synthesis and crystal structure of a solvated Co(III) complex with 2-hy-droxy-3-meth-oxy-benzaldehyde thio-semicarbazone ligands.

The title Co(III) complex, bis-[bis-(2-hy-droxy-3-meth-oxy-benzaldehyde thio-semi-carbazonato)cobalt(III)] di-thio-nate-dimethylformamide-methanol (1/4/3), [Co(C(9)H(10)N(3)O(2)S)(2)](2)(S(2)O(6))·4C(3)H(7)NO·3CH(3)OH, with monodeprotonated 2-hy-droxy-3-meth-oxy-benzaldehyde thio-semicarbazone as ligands crystallizes in the space group P . The asymmetric unit consists of two mononuclear [CoL (2)](+) cations, one di-thio-nate anion (S(2)O(6))(2-) as counter-anion and seven solvate mol-ecules (four di-methyl-methanamide and three methanol). Each Co(III) ion has a moderately distorted octa-hedral S(2)N(2)O(2) geometry. In the crystal, the components are linked by numerous N-H⋯O and O-H⋯O contacts.
