Crystal structure of the co-crystalline adduct 1,3,6,8-tetra­aza­tri­cyclo­[4.4.1.1(3,8)]dodecane (TATD)–4-iodo­phenol (1/2): supra­molecular assembly mediated by halogen and hydrogen bonding

The asymmetric unit of the title co-crystalline adduct, 1,3,6,8-tetra­aza­tri­cyclo[4.4.1.1(3,8)]dodecane (TATD)–4-iodo­phenol (1/2), C(8)H(16)N(4)·2C(6)H(5)IO, comprises a half mol­ecule of the aminal cage polyamine plus a 4-iodo­phenol mol­ecule. A twofold rotation axis generates the other half of the adduct. The components are linked by two inter­molecular O—H⋯N hydrogen bonds. The adducts are further linked into a three-dimensional framework structure by a combination of N⋯I halogen bonds and weak non-conventional C—H⋯O and C—H⋯I hydrogen bonds.
