Thermochemistry of aniline-derivative adducts of nickel(II) acetylacetonate

, p. 5 - 11 (1999)
The compounds [Ni(acac)2(L)2] (where acac is acetylacetonate and L is aniline (an), 2,6-dimethylaniline (dimean), o- or m-chloroaniline (o- or m-clan)) were synthesized and characterized by melting points, elemental analysis, TG-DTG, and DSC curves and electronic and IR spectroscopy. The enthalpies of dissolution of the adducts, Ni(II) acetylacetonate and ligands in a 1 : 3 (v/v) mixture of aqueous HCl 1.2 M and methanol, were measured and by using thermochemical cycles the following thermochemical parameters for the adducts have been determined: The standard enthalpies for the Lewis acid/base reaction (ΔrHθ), the standard enthalpies of formation (ΔfHθ), the standard enthalpies of decomposition (ΔDHθ), the lattice standard enthalpies (ΔMHθ) and the standard enthalpies of the Lewis acid/base reactions in the gaseous phase (ΔrHθ(g)). The mean standard enthalpies of the nickel-nitrogen bonds have been estimated.
