Abstract
Abstract The monoclinic form of diaquobis(acetylacetonato)nickel(II) is well known; however, the existence of the triclinic monohydrate form is not well recognized although preparations of the diaquo complex yield predominantly the monohydrated species when water is present in excess amounts. Diaquobis(acetylacetonato)nickel(II) monohydrate has a unit cell of dimensions a=9.083 A, b=11.012 A, c=7.578 A, α=95.85°, β=92.12° and γ=106.00° and contains two molecules related by a center of symmetry. 3,122 pieces of three-dimensional intensity data (CuKα) were collected using an automated diffractometer. The structure was solved by conventional Patterson and Fourier techniques and was refined by least squares methods to a conventional R of 0.09. The structure is that of the hydrate water molecule hydrogen bonded predominantly to the acetylacetone oxygens of the diaquobis(acetylacetonato)nickel(II) molecule. The structure of the diaquobis(acetylacetonato)nickel(II) molecule obtained in this study is compared to ...
