| Popis: | The 181 Ta NMR spectra of solutions of [Et 4 N][TaL 6 ] (L = Cl − , CO) and K 2 [TaF 7 ] have been obtained. The shift range encompasses 3450 ppm, limited by [TaCl 6 ] − at the low-field and [Ta(CO) 6 ] − at the high-field side. The shielding sensitivity of the 181 Ta nucleus is about 1.6 times that of 93 Nb and 0.6 times that of 183 W. Half widths are 4.3 (L = Cl − ), 6.7 (L = CO) and 29 kHz ([TaF 7 ] − ). |
