Additional NMR Experimental Information
1 THE STRUCTURE WAS DETERMINED USING TRIPLE-RESONANCE NMR SPECTROSCOPY. 20 STRUCTURES IN THE DEPOSITION WERE FITTED BY FITTING STRUCTURES 2-20 TO THE FIRST, USING PROFIT V1.8 (MCLACHLAN, A. D., 1982 ACTA. CRYST.A38, 871-3) AS IMPLEMENTED IN THE PROGRAM PROFIT (MARTIN, A. C. R.,HTTP:// WWW.BIOCHEM.UCL.AC.UK/~MARTIN/PROGRAMS/#PROFIT)
