Ni(Il) complexes The allowed values are then substituted in to the modified van Vleck equation, eqn. (4), N 2 2 25' s'+1 2s'+1 -E< 104 emu mol" for fitting of both compounds, a typical value for Ni, complexes [22]. Where R is the agreement factor calculated as R = [Z(,1'0bs_ - ZCa,c.)2 / Z Z0bs_2]'/2. The coupling constant J obtained for both 2 and 3 are consistent with intramolecular antiferromagnetic interactions between the Ni(H) electron spins. Relatively high J (negative) values are suggestive of strong (4) 115
Chapter 3 antiferromagnetic coupling. For complex 4 (the temperature dependence curves of X,“ and um are shown in Fig. 3.32), however, we could not get a reasonable fit, may be associated with zero-field splitting (D) especially at lower temperatures and/or due to slight variations in M—X—M angles, so that more J values need to be considered. The M—O—M arrangement at 180° is known as an ideal structure for strong antiferromagnetism [55]. This linearity as the origin of strong AF coupling is in accordance with VB [56-58] and MO [59] studies. Logically, Kahn also explained this feature in his book [60]. The temperature dependence of effective magnetic moment curves for complexes 1 and 4 are also consistent with these results, though lacks reasonable fits. We have reported these results recently [61]. The field dependence of magnetic susceptibility 6 for these compounds (Fig. 3. 33) not showed any indication of ferromagnetic __ component and is in agreement /(.1 with overall antiferromagnetism. 8-.
