چکیده
The mol-ecule of the title compound, C(18)H(28)N(2), composed of two 2,5-dimethyl-pyrrole groups linked by a hexane chain, lies across a crystallographic inversion centre. The mean plane of the pyrrole ring is almost perpendicular to the mean plane of the central chain, making a dihedral angle of 89.09 (8)°. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions.

In the title compound, C(25)H(32)Cl(2)N(2)O(2), there are two intra-molecular O-H⋯ N hydrogen-bonding inter-actions between the hy-droxy groups on the aromatic rings and the two N atoms of the heterocyclic group. The cyclo-hexane ring adopts a chair conformation and the imidazolidine unit to which it is fused has a twisted envelope conformation. The asymmetric unit comprises one half-mol-ecule ...
