摘要:
A number of lead(II) O,O'-dialkyldithiophosphate complexes were studied by C-13, P-31, and Pb-207 MAS NMR. Simulations of P-31 chemical shift anisotropy using spinning sideband analysis reveal a linear relationship between the S-P-S bond angle and the principal values delta(22) and delta(33) of the P-31 chemical shift tensor. The P-31 CSA data were used to assign ligands with different structural functions. In the cases of diethyldithiophosphate and di-iso-butyldithiophosphate lead(II) complexes, (2)J(P-31, Pb-207)-couplings were resolved and used to confirm the suggested assignment of the ligands. The SIMPSON computer program was used to calculate P-31 and Pb-207 spectral sideband patterns. (c) 2005 Elsevier Inc. All rights reserved.
