Abstract
The 13C CP MAS NMR spectrum of [( n-C 3H 7) 4N][Cd(SCN) 3], 1, indicates the presence of three non-equivalent thiocyanate ligands, in agreement with the results of a recent single-crystal X-ray diffraction study. Examination of the 13C MAS line shapes allows direct measurement of the indirect spin-spin coupling constants, 1J ( 14N, 13C) = 16 ± 1 Hz and 2J( 111 113 Cd, 13C) = 75 ± 5 Hz , for the unique N-bonded thiocyanate ligand. This is the first reported measurement of 1J ( 14N, 13C) and 2J( 111 113 Cd, 13C) in the solid state. Possible reasons for the failure to observe 1J ( 14N, 13C) values in previous high-resolution 13C CP MAS NMR studies are summarized.
