Chapter 4 The solid state and some frozen DMF spectra recorded in a Varien E 112 EPR spectrometer in the X-band were very broad with no good hyperfine splittings. These kinds of spectra do not give much information but may be the presence of antiferromagnetic interaction between copper(II) ions. Some of the room temperature powder spectra however exhibit some indications of weak triplet state lines at half fields of Cu(H)...Cu(H) interactions. So far, reports of EPR measurement of Cu(H) complexes of thiocarbohydrazone [12] and carbohydrazone [17] unfortunately do not give much information. The dimeric dicopper(H) compound of a similar thiocarbohydrazone [12] in H3PO4 frozen solution shows two monomeric axial Cu(H) species, one with a g" value of 2.33, somewhat similar behaviour of our study. The absence of any detailed EPR studies of similar multinuclear carbohydrazone or thiocarbohydrazone Cu(H) complexes with single crystal X-ray results for molecular structural corroborative studies still leaves the matter for further research. A detailed analysis of the EPR behavior by varying concentration in different solvents is found obligatory to get a clearer picture of labile multinuclear systems. 4.3.5. Magnetochemistry For all the copper compounds the temperature dependence of molar magnetic susceptibility X,“ in the powder form is carried out in the temperature range 5-325 K. All compounds are found to show common features. The effective magnetic moments pm at room temperature of all dicopper(H) compounds are found to be low or near compared to that expected for two independent Cu(II) ions (2.45 pg) and also shows a regular decrease with decreasing temperature suggesting antiferromagnetic interactions between Cu(H) ions. The temperature dependence curves of 8, 9 and 13 also show similar nature. These features indicate a dominant antiferromagnetic interaction in these compounds. Also it is found that Curie law is not obeyed by all systems, in agreement with the exchange coupling. 170
