What is Synthesis, molecular structure and magnetic properties of di-μ-hydroxo-bis-(bis(1,3-bis(2-hydroxyphenyl)-1,3-propanedione)chromium(III)) bistoluene about?

The title compound [CrZ(bhppH&(0H)J\*2C,Hs has been synthesized and isolated by chromatographic techniques from the reaction between 1,3-bis(2hydroxyphenyl)-1,3-propanedione (bhppHs) and Cr(N03)a.9Hz0. Well formed single crystals were grown from toluene solutions and characterized by Xlray diffraction methods being triclinic, space group Pl , with a = 12.692( 2), b = 13.423(2), c = 2 1.983(4) A, (Y= 102.24(l), /3=92.04(l), y= 115.72(l)", V= 3.262(6) A3, 2~2, D,= 1.370 g cm-3 and p=3.9 cm-. ' , F(OO0) = 1.396. Magnetic susceptibilities were measured from 50 down to 4.2 K and fitted using the simplest Hamiltonian for exchange coupled systems x = -2JSiS2. The best results were obtained with J= -4.1 cm-' and g = 1.85. These values are compared with the Glerup, Hodgson and Pedersen (GHP) model.
