Chapter 4 The field dependence of magnetic susceptibility for compounds 8 and 9 at 5 and 300 K were studied (Figs. 4. 52 and 4.53), however, do not show any indication of ferromagnetic component and is in agreement with overall antifrromagnetism. For complex ll, the susceptibility varies considerably between 55 to 85 K, and for 17 a variation is seen in between 70 and 85 K. However, the general nature of the susceptibility curves of all complexes are consistent with strong coupling interactions between Cu(II) electrons through their connecting moiety. The rapid increase in Xm for ‘I I . . . some compounds at low temperature is due to monomer impurity. 0.4-I T 0.3% ~ | - _ 0.20 ‘I ‘ . " 0.15 1 ‘ InI ~ i _ . I.’ -0.3 '0.15 .
