Abstract:
The reaction of EuX3 ·nH2O (X=Cl¯ , NO3¯ ), a- pyridoin anion (P) and 2,2¢-dipyridylamine in ethanol solution yields a hydroxo complex, EuP2(OH) 2(H2O) 2, which is characterized by NMR, IR, and elemental analyses. Europium complexes coordinated by nitrogen donating ligands such as 2,2¢-dipyridylamine or 2¢-hydroxypyridine are unstable in solution and are prone to decompose to europium hydroxo complex and pyridinium amine salt. The UV and PL spectra of europium complexes are reported and a decomposition mechanism is proposed.
