TY - JOUR A1 - Rivera, Augusto A1 - Rojas, Jicli José A1 - Sadat-Bernal, John A1 - Ríos-Motta, Jaime A1 - Bolte, Michael T1 - Mechanochemical synthesis and crystal structure of a 1:2 co-crystal of 1,3,6,8-tetraazatricyclo-[4.3.1.13,8]undecane (TATU) and 4-chloro-3,5-dimethylphenol T2 - Acta crystallographica. Section E, Crystallographic communications N2 - Solvent-free treatment of 1,3,6,8-tetra­aza­tri­cyclo­[4.3.1.13,8]undecano (TATU) with 4-chloro-3,5-di­methyl­phenol led to the formation of the title co-crystal, C7H14N4·2C8H9ClO. The asymmetric unit contains one aminal cage mol­ecule and two phenol mol­ecules linked via two O-H...N hydrogen bonds. In the aminal cage, the N-CH2-CH2-N unit is slightly distorted from a syn periplanar geometry. Aromatic [pi]-[pi] stacking between the benzene rings from two different neighbouring phenol mol­ecules [centroid-centroid distance = 4.0570 (11) Å] consolidates the crystal packing.
