DTA studies on the liquidus temperatures of Cr complex with the addition of an anhydrous Ni complex

Determination of T-X-Cr diagram for a binary system of tris(2,4-pentanedionato)Cr(III) and anhydrous bis(2,4-pentanedionato)Ni(II) over the range of 1.000-0.506 for the mole fraction (X-Cr) of the Cr complex by employing DTA revealed the system to behave as an ideal eutectic exhibiting lowering of the melting point of the former complex with the addition of the latter one. The thermodynamic correlation between T and X-Cr yielded an average value of 109.9 +/- 0.4 kJ mol(-1) for the standard enthalpy of fusion of the Cr complex. (C) 2003 Elsevier B.V All rights reserved.
