STRUCTURE OF 13,13'-(1,4- PHENYLENEBIS(METHYLENE))BIS-1,4,7,10-TETRAOXA-13- AZACYCLOPENTADECANE DIHYDROCHLORIDE, A BICYCLIC MACROCYCLE CONTAINING TWO (15)-NO-4 SUBUNITS LINKED BY AN AROMATIC GROUP
C-28H-50N-2O2+/8-.2C1-,M-r=613.6, monoclinic, P2-1/c,a = 9.873 (3), b = 10.823 (3), c = 15.823 (9) ALPHA, beta = 108.26 (4) degrees, V = 1606 (5) ALPHA3, Z = 2, D-x = 1.269 g cm-3, lambda(Mo Kalpha) = 0.71073 ALPHA, mu = 2.468 cm-1, F(000) = 660, T = 295 (1) K, final R = 0.034 for 1249 observed reflections. The title compound contains two identical monoaza tetraoxa 15- membered macrocycles linked by a p-xylylene bridge. As expected for odd-membered rings, the two binding subunits display an irregular geometry and only part of their confirmational arrangement is found in the structures already reported for other 15-membered macrocycles. The molecular symmetry is 1 (C-i).
