چکیده
In the title compound, C7H14N4·2C6H5ClO, which crystallized with two crystallographically independent 4-chloro-phenol mol-ecules and one 1,3,6,8-tetra-aza-tri-cyclo-[4.3.1.13,8]undecane (TATU) mol-ecule in the asymmetric unit, the independent components are linked by two O-H⋯N hydrogen bonds. The hydrogen-bond acceptor sites are two non-equivalent N atoms from the aminal cage structure, and the tricyclic system distorts by changing the C-N bond lengths. In the crystal, these hydrogen-bonded aggregates are linked into chains along the c axis by C-H⋯N hydrogen bonds. The crystal structure also features C-H⋯π contacts.

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
Solvent-free treatment of 1,3,6,8-tetra-aza-tri-cyclo-[4.3.1.13,8]undecano (TATU) with 4-chloro-3,5-di-methyl-phenol led to the formation of the title co-crystal, C7H14N4·2C8H9ClO. The asymmetric unit contains one aminal cage mol-ecule and two phenol mol-ecules 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. Aro...

In the title ternary co-crystalline adduct, C7H14N4·2C6H5NO3, mol-ecules are linked by two inter-molecular O-H⋯N hydrogen bonds, forming a tricomponent aggregates in the asymmetric unit. The hydrogen-bond formation to one of the N atoms is enough to induce structural stereoelectronic effects in the normal donor→acceptor direction. In the title adduct, the two independent nitro-phenol mol-ecules...
