STRUCTURE OF 11,14,27,30,35,38,43,46-OCTAOXA - 1,8,17,24-TETRAAZAPENTACYCLO - (184.108.40.206.8,17.2.3,6.2.19,22)-DOPENTACONTA - 3,5,19,21,49,51-HEXENE, C-40H-64N-4O-8, A TRICYCLIC MACROCYCLE FEATURING TWO 18-N-2O-4 BINDING SUBUNITS AND TWO BENZENE BRIDGES
M-r = 728.98, Ppdelta 1, a = 8.823(3), b = 8.813(4), c=13.859 ANGSTROEM, alpha=87.40, beta=84.05, gamma = 85.19(1) degrees, V = 1067.3 ANGSTROEM**3, Z = 1, D-x = 1.134 Mg m**-3-, Mo K-a, lambda = 0.71073 ANGSTROEM, upsilon = 0.0735 mm**-1, F(000) = 396, T-293 K, final R = 0.048 for 2124 observed reflections. The title compound is a tricyclic cryptand with an internal cavity defined by two parallel 18- membered [C-12H-24N-2O-4] macrocyclic units bridged by two parallel phenyl rings. The structure is consistent with the results obtained for a similar compound with two naphthalene bridges. However, the conformation of themacrocyclic subunit differs significantly from that of the free monocyclic analogue.
