Bis[3α,7α,12α-tris­(4-nitro­benzo­yloxy)-5β-cholan-24-yl] disulfide–ethyl acetate–n-hexane (4/4/1)

The crystal structure of the title compound, C(90)H(100)N(6)O(24)S(2)·C(4)H(8)O(2)·0.25C(6)H(14), solved and refined against synchrotron diffraction data, contains two formula units in the asymmetric unit with the all-trans n-hexane mol­ecule having half-occupancy and one of the ethyl acetate mol­ecules disordered over two positions. The two symmetry-independent disulfide mol­ecules are assembled by approximate face-to-face and face-to-edge inter­actions between their 4-nitro­benzo­yloxy groups into an inter­twined dimer having a double-helix-type structure. The centrally placed disulfide bridges in the two symmetry-independent mol­ecules exhibit different helicity as shown by the C—S—S—C torsion angles of 71.0 (1) and −92.5 (1)°.
