Topochemistry of Polymer-Bonded Paramagnetic Complexes

Polymer-bonded paramagnetic complexes provide the most information about topochemistry. Cu +, Mn , and other ions are used most as paramagnetic cen- 

The Weiss constant (9) is equal to 5 OK. This can be explained by the presence of two types of bond complexes for Cu + isolated complexes (that obeys the Curie law), and complexes that aggregate into clusters with an antiferromagnetic exchange. This 

The copper content in theses complexes is estimated by the equation 

Total Cu Content, % Content, % Cu Density in Clusters XlO o, cm-3 Total Cu Content, % Content, % Cu Density in Clusters X 10 , cm-3 

The experimental data show that at a concentration C,otai = 0.1 mmole/g, more than half of the copper ions is localized in cluster aggregatims (Table 4). More detailed information can be obtained from the ESR spectra. As Cjotai increases, the shape of the ESR spectrum is changed (Fig. 6) a wide asymmetrical singlet appears and grows.
