摘要：

Eight binary and ternary solid complexes of EU3+ with pyridine-2, 6-dicarboxylic acid (H2DPC), 1,10-phen-anthroline (phen) and methylbenzoic acid (MBA), including o-MBA, m-MBA and p-MBA, were synthesised. Their compositions were confirmed by elemental analysis. The coordination mode of ligands with EU3+ was studied by NMR and IR. The coordination number of eight complexes was also investigated. Furthermore, the influence on chemical shift and NMR spectrum shape by induction effect, screening effect acid paramagnetic character of EU3+ were discussed in detail.
