Crystal structure of a methanol solvate of a macrocycle bearing two flexible side-arms

Di-tert-butyl N,N′-{[13,15,28,30,31,33-hexa­ethyl-3,10,18,25,32,34-hexa­aza­penta­cyclo­[25.3.1.1(5,8).1(12,16).1(20,23)]tetra­triaconta-1(31),3,5,7,9,12(33),13,15,18,20,22,24,27,29-tetra­deca­ene-14,29-di­yl]bis­(methyl­ene)}dicarbamate methanol disolvate, C(52)H(72)N(8)O(4)·2CH(3)OH, was found to crystallize in the space group P2(1)/c with one half of the macrocycle (host) and one mol­ecule of solvent (guest) in the asymmetric unit of the cell, i.e. the host mol­ecule is located on a crystallographic symmetry center. Within the 1:2 host–guest complex, the solvent mol­ecules are accommodated in the host cavity and held in their positions by O—H⋯N and N—H⋯O bonds, thus forming ring synthons of graph set R (2) (2)(7). The connection of the 1:2 host-guest complexes is accomplished by C—H⋯O, C—H⋯N and C—H⋯π inter­actions, which create a three-dimensional supra­molecular network.
