Usage

Uses

Used in NMR Spectroscopy:
PR(TMHD)3 is used as an NMR shift reagent for enhancing the resolution and identification of chemical species in nuclear magnetic resonance (NMR) spectroscopy. Its paramagnetic nature allows for the differentiation of closely related compounds and provides valuable information about the molecular structure and interactions.
Used in Superconductivity Research:
PR(TMHD)3 is used as a precursor in the preparation of superconductive materials, such as gallium praseodymium oxide (PrGaO3) thin films. These materials exhibit unique properties, including zero electrical resistance and expulsion of magnetic fields, which have potential applications in various fields, including energy transmission, magnetic levitation, and quantum computing.

Crystal Structures of [Dy(dpm)3]2 and Dy(dpm)3, Luminescent and X-Ray Fluorescent Study of Lanthanide(III) Tris-Dipivaloylmethanates

Crystal structures of [Dy(dpm)3]2 (1) at 155(2) K (space group P21/n, a = 12.2191(3) ?, b = 27.6044(6) ?, с = 21.8615(5) ?, β = 105.172(1)°, V = 7116.9(3) ?3, Z = 4) and Dy(dpm)3 (2) at 200(2) K (space group Pmn21, a = 17.8741(7) ?, b = 10.5639(4) ?, с = 9.8336(4) ?, V = 1856.78(13) ?3, Z = 2) are determined. The structure of complex 1 is similar to the previously known dimeric packings [Ln(dpm)3]2 (Ln = La, Pr, Nd, Eu, Gd, Tb). Complex 2 is isostructural to the previously studied molecular complexes Er(dpm)3 and Lu(dpm)3. At room temperature the luminescence quantum yield (QY) of Tb(dpm)3 is found to reach 77% and that of Dy(dpm)3 is 5%, while for the other Lu(dpm)3 complexes, where Ln = Pr, Nd, Sm, Eu, Gd, Ho, Er, Tm, Yb, QY is below 1%. A series of [Tb(dpm)3]2 and Dy(dpm)3 solid solutions is obtained by evaporating mixtures from solutions. Molecular films of these complexes on Si, Cu, Ni, Ti, KBr substrates are obtained by vacuum deposition.
