A new trisdithiolene vanadium(IV) complex has been synthesized and characterized. The enantionieric anion units, [V(dbddto)(3)](2-), are packed so closely that the sulfur-rich planar ligands stack to form a honeycomb sheet structure, resulting, in the creation of large cavities (12 x 5.5 angstrom) for guests. The magnetic susceptibilities show ail existence of antiferromagnetic interaction in spite of the large interatomic separation of the vanadium ions (V...V distance = 11.069 angstrom (av.)), associated with the interaction between the stacking ligand pathway in the honeycomb sheet.
