✦ Synopsis

The structure of the title complex, [Ni 2 (C 5 H 7 O 2 ) 4 (H 2 O) 2 ]Á-0.5H 2 O, is dimeric and corresponds to the trimeric structure of bis(acetylacetonato)nickel(II) in which one Ni(acac) 2 unit is replaced by two water molecules. The centrosymmetric molecule comprises two O-O edge-shared octahedra. The asymmetric unit contains two half-molecules of the complex and one water molecule.
