Bis[μ-pentane-2,4-dionato(1−)]bis{aqua[1,1,1,5,5,5-hexafluoropentane-2,4-dionato(1−)]cobalt(II)}

The title complex, [Co2(C5HF6O2)2(C5H7O2)2(H2O)2], is centrosymmetric with a crystallographic inversion center in the middle of the molecule. The octahedrally coordinated CoII atoms are bridged by two chelating acetylacetonate (acac) ligands and two more electron-poor 1,1,1,5,5,5-hexafluoropentane-2,4-dionato (hfac) ligands are bonded terminally in a solely chelating manner. The coordinated water molecules form intermolecular O—H...O hydrogen bonds with electron-rich acac O atoms of neighboring molecules, leading to strings of molecules along the a axis
