Additional NMR Experimental Information
Details	This structure was determined using 2D and 3D homonuclear techniques. This structure represents a refinement of the structure originally published in secondary citation #1 (Qian, X. and Weiss, M.A.). Additional constraints were determined using higher-concentration samples and by homonuclear 3D-NMR methods.
