We performed several NMR studies, particularly H-1, C-13, 2D NOESY and DOSY, at various temperatures on 500 and 950 MHz instruments. We discovered that the complex 3 is unstable above 57 degrees C in heavy water, while it is kinetically stable enough to be studied by NMR in detail at 1 degrees C. We demonstrated the formation of a face-to-face 2:1 complex with a binding constant of approximately 2.2 x 10(6) M-2. ER -
