title: (2RS,3SR,10SR,11RS)-3,10-Diphen-oxy-18,21-dioxa-5,8-diaza-penta-cyclo-[20.4.0.0.0.0]hexa-cosa-1(26),12,14,16,22,24-hexa-ene-4,9-dione ethyl acetate hemisolvate.
abstract: In the title compound, C(34)H(30)N(2)O(6)·0.5C(4)H(8)O(2), there are two mol-ecules in the asymmetric unit and the structure is stabilized by C-H⋯O inter-actions. The two nonsolvent mol-ecules of the asymmetric unit are linked together by a weak C-H⋯O hydrogen bond. The ethyl acetate mol-ecule is present as a space filler and does not participate in the hydrogen-bonding network.
