Three new lanthanide phenoxyacetate complexes with 1,10‐phenanthroline. [Nd(POA) 3 (phen)] 2 · 2C 2 H 5 OH (1), [Eu(POA) 3 ‐ (phen)] 2 · 2C 2 H 5 OH (2) and [Sm(POA) 2 (DMSO)(phen)] 2 ‐ (ClO 4 ) 2 (3) (POA= phenoxyacetate, phen = 1,10‐phenanthroline, DMSO = dimethyl sulfoxide), were synthesized and characterized by elemental analyses, IR, UV‐vis and FAB‐MS spectra. Their structures were determined by single crystal X‐ray diffraction analysis. In complexes 1 and 2, the carboxylate groups are bonded to Ln 3+ ion in three modes: the chelating bidentate, the bridging bidentate and the bridging tridentate. In complex 3, the carboxylate groups are bonded to Sm 3+ ion only involved in one mode: the bridging bidentate. The luminescence behavior of complex 2 was also studied by means of emission spectra.
