| Popis: | Syntheses for new potentially chelating ligands, 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine 1-oxide (2), ((6-((1H-pyrazol-1-yl)methyl)pyridin-2-yl)methyl)diphenylphosphine oxide (4) and 2-((1H-pyrazol-1-yl)methyl)-6-((diphenylphosphoryl)methyl)pyridine 1-oxide (5), that are based upon pyridine or pyridine N-oxide platforms functionalized with pyrazol-1-ylmethyl and diphenylphosphinoylmethyl substituents, are reported along with results from molecular modeling analyses that assess the strain energy encountered by the ligands in tridentate chelate interactions for gas phase [Eu(L)3+]complexes. Coordination chemistry with selected lanthanide nitrates is described along with X-ray crystal structure determinations for the three ligands and three representative coordination complexes. |
