Solid-State 17O NMR Spectroscopy of Paramagnetic Coordination Compounds

Angewandte Chemie International Edition  by Xianqi Kong, Victor V. Terskikh, Rahul L. Khade, Liu Yang, Amber Rorick, Yong Zhang, Peng He, Yining Huang, Gang Wu  /   11d   //   keep unread   //   hide   //   preview Abstract High-quality solid-state  17 O (I=5/2) NMR spectra can be successfully obtained for paramagnetic coordination compounds in which oxygen atoms are directly bonded to the paramagnetic metal centers. For complexes containing V III  ( S =1), Cu II  ( S =1/2), and Mn III  ( S =2) metal centers, the  17 O isotropic paramagnetic shifts were found to span a range of more than 10 000 ppm. In several cases, high-resolution  17 O NMR spectra were recorded under very fast magic-angle spinning (MAS) conditions at 21.1 T. Quantum-chemical computations using density functional theory (DFT) qualitatively reproduced the experimental  17 O hyperfine shift tenso...
