Crystal structure of bis(μ-{2-[(5-bromo-2-oxido-benzyl-idene)amino]-eth-yl}sulfanido-κ³ N,O,S){2,2'-[(3,4-di-thia-hexane-1,6-di-yl)bis-(nitrilo-methanylyl-idene)]bis-(4-bromo-phenolato)-κ⁴ O,N,N',O'}dicobalt(III) di-methyl-formamide monosolvate.

ABSTRACT: The title binuclear Co^III complex, [Co₂(C₉H₈BrNOS)₂(C₁₈H₁₆Br₂N₂O₂S₂)]·C₃H₇NO, with a Schiff base ligand formed in situ from cyste-amine (2-amino-ethane-thiol) and 5-bromo-salicyl-aldehyde crystallizes in the space group P2₁. It was found that during the synthesis the ligand undergoes spontaneous oxidation, forming the new ligand H₂ L' having an S-S bond. Thus, the asymmetric unit consists of one Co₂(L)₂(L') mol-ecule and one DMF solvent mol-ecule. Each Co^III ion has a slightly distorted octa-hedral S₂N₂O₂ coordination geometry. In the crystal, the components are linked into a three-dimensional network by several S⋯ Br, C⋯ Br, C-H⋯Br, short S⋯C (essentially shorter than the sum of the van der Waals radii for the atoms involved) contacts as well by weak C-H⋯O hydrogen bonds. The crystal studied was refined as an inversion twin.

Project description:The crystal structure of the title compound, [Cu2(C18H12Br2N4O2S2)2], consists of binuclear complex units which lie across inversion centres and are connected by weak Cu-O coordination bonds forming chains along the b axis. The CuII ion is five-coordinated by two N atoms and two O atoms of the chelating ligand and one symmetry-related O atom forming a square-pyramidal coordination geometry. In the crystal, short S⋯Br contacts connect neighbouring chains into a two-dimensional network parallel to (101).

Project description:In the title compound, C(20)H(22)N(2)O(2), the asymmetric unit contains two independent half-mol-ecules, which are both completed by crystallographic inversion symmetry.

Both mol-ecules feature two intra-molecular O-H?N hydrogen bonds, which generate S(6) rings.
