Abstract
The title complex, [Co(2)(C(5)HF(6)O(2))(2)(C(5)H(7)O(2))(2)(H(2)O)(2)], is centrosymmetric with a crystallographic inversion center in the middle of the mol-ecule. The octa-hedrally coordinated Co(II) atoms are bridged by two chelating acetyl-acetonate (acac) ligands and two more electron-poor 1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato (hfac) ligands are bonded terminally in a solely chelating manner. The coordinated water mol-ecules form inter-molecular O-H⋯O hydrogen bonds with electron-rich acac O atoms of neighboring mol-ecules, leading to strings of mol-ecules along the a axis.
