Study of the crystal structure of binuclear boron difluoride acetylacetonate

The molecular and crystal structure of binuclear boron difluoride acetylacetonate, in which two boron chelate moieties are linked by a disulfide group, is determined. It is found that in the crystalline state, the chelate moieties are non-equivalent. The differences identified stem from the fact that molecules crystallize in pairs: two chelate ring (one from each molecule of the pair) are linked with each other by the stacking interaction. The other chelate rings of the pair do not participate in intermolecular interactions.
