    • Kα radiation. Distances are O(18)-N(36) 2.829(6), O(18)-O(54) 2.710(7), O(21)-N(35) 2.871(5), O(21)-N(45) 2.912(5), O(22)-N(46) 2.848(6), N(33)-O(54) 3.037(7), N(43)-O(52) 2.886(7), N(46)-O(51) 2.890(7), O(51)-O(52) 3.167(10), N(35)-N(15) 3.060(5), N(36)-N(16) 2.999(4) Å. Individual host and guest moieties are connected by intermolecular hydrogen bonds between O(19) and N(45) (symmetry element 1-x,-y,2-z), distance 2.936(6) Å, to form a helix. Other hydrogen bonds involving water molecules are also present in the unit cell (O(18)⋯O(52) (2-x,-y, 2-z) 2.882(8), O(19)⋯O(53) (x,y,1 + z) 2.753(6), O(19)⋯O(51) (x-1, y + 1, z) 2.936(7), O(21) ⋯O(53) (1 - x, - y, 1 - z) 2.817(6) Å), as are water- water hydrogen bonds.
