| Abstract: | <p>The nuclear magnetic resonance of <sup>31</sup>p has been studied in Mn<sub>2</sub>P<sub>2</sub>O<sub> 7</sub>, Co<sub>2</sub>P<sub>2</sub>O<sub>7</sub>, Cu<sub>2</sub>P<sub>2</sub>O<sub>7</sub> and Ni<sub>2</sub>P<sub>2</sub>O<sub>7</sub>. The resonances were found to be shifted from the predicted field due to the delocalization of unpaired electrons from the paramagnetic ions. The fraction of an unpaired electron present in the phosphorus 3s orbital arising from each metal-oxygen-phosphorus transfer path is 0.110% in Mn<sub> 2</sub>P<sub>2</sub>O<sub>7</sub> and ~ 0.05% in the other compounds studied. The difference in these values is discussed in terms of the structure and bonding of the P<sub>2</sub>O<sub>7</sub><sup>4-</sup> anions.</p> |
