    • For Cu(25-dimethylpyrazine)Cl2, magnetic data are fitted to 2Jintra=-20K=-13.9 cm-1, and 2J0inter=-4K=-2.8 cm-1 with J0/J=0.20 For Cu(2, 5-dimethylpyrazine)Br2 larger values of J exchange interaction are found. Turnbull, M.M. Private communication. Notice that, because Cu2+-Cl-3 3 3 Cl-Cu2+ and Cu2+-Br-3 3 3 Br-Cu2+ magnetic interactions depend on the distance and orientation of the interacting fragments, some of them are strong and others can be very weak

    • note
    • The relative stability between the lowest-energy states of a given multiplicity increases as S is increased; that is, ELS(S=0). The formation of bands (states separated by energy gaps smaller than the thermal energy) is observed when large enough chains are used in the computations
