Single X-ray crystallography showed that the complexes displayed 8-coordinated geometry. The solid pyridyl adducts 2-4 exhibited emission of luminescence in the NIR and visible regions with close quantum yields (QY = 0.20-0.25%). The magnetic data of 1-4 showed larger values than those expected for magnetically noncoupled Sm(III) complexes in the 6H5/2 ground state, with no saturation on the applied high magnetic field static at a temperature of 2 K.application/pdfengcc-by (c) Mautner, Franz A. et al., 2022https://creativecommons.org/licenses/by/4.0/LuminescènciaPropietats magnètiquesRaigs XLuminescenceMagnetic propertiesX-raysinfo:eu-repo/semantics/article7247292023-01-10info:eu-repo/semantics/openAccess
