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

The title CoIII complex, bis-[bis-(2-hy-droxy-3-meth-oxy-benzaldehyde thio-semi-carbazonato)cobalt(III)] di-thio-nate-dimethylformamide-methanol (1/4/3), [Co(C9H10N3O2S)2]2(S2O6)·4C3H7NO·3CH3OH, 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 (S2O6)2- as counter-anion and seven solvate mol-ecules (four di-methyl-methanamide and three methanol). Each CoIII ion has a moderately distorted octa-hedral S2N2O2 geometry. In the crystal, the components are linked by numerous N-H⋯O and O-H⋯O contacts.
