Nanotubular non-covalent macrocycle within non-covalent macrocycle assembly: (MeOH)12 encapsulated in a molecular clip cyclododecamer

Dimeric packing of molecular clips induced by interactions between π-systems

We report the first observation synthesis and X-ray structures of seven glycoluril clips that feature extended aromatic sidewalls; compounds 1 and 2 are the first examples of the out–out dimeric motif.

(4R,11R)-9-(1-hydroxypropan-2-yl)-4,11-diphenyl-1,3,5,7,9-pentaazatri-cyclo[5.3.1.0]undecane-2,6-dithione

The asymmetric unit of the title compound, C₂₁H₂₃N₅OS₂, contains two independent chiral mol­ecules. The two phenyl rings of one mol­ecule form a dihedral angle of 51.95 (7)° and the distance between their centroids is 4.345 (1) Å. In the other mol­ecule, the phenyl rings form a dihedral angle of 58.79 (8)° with a ring centroid–centroid distance of 4.435 (2) Å. An intra­molecular O—H⋯N hydrogen bond occurs in each independent mol­ecule. The crystal packing is stabilized by and inter­molecular N—H⋯O and N—H⋯S hydrogen bonds and C—H⋯S inter­actions.
