Synthesis and Spectral Characterisation of Lanthanide(III) Complexes of Trimethoprim

Abstract

A new series of hepta coordinated lanthanide(III) complexes of the type [ML2Cl3] (where M = LaIII, PrIII, NdIII, SmIII, GdIII, TbIII, DyIII or YIII, L = trimethoprim) have been synthesised. The new complexes were characterised using various physico-chemical methods such as elemental analysis, spectral (IR, UV–VIS, 1H NMR), magnetic and X-ray diffraction analysis. A monocapped trigonal prism structure has been tentatively proposed for the complexes.
