| Popis: | The title compound, C₁₄H ₁₇N₃ O, prepared from (1R,2S)- (-)-ephedrine, crystallizes in space group P2₁ with four molecules in the asymmetric unit. The molecules, in pairs, take part in intermolecular N--H...N hydrogen bonding between the imidazolyl rings, forming one-dimensional chains with alternating N...N distances of 2.866 (3)/2.883(3) and 2.945 (3)/2.956(3)Å. Inter-chain Carene--H...πarene, Carene--H...O and Csp3--H...πc= interactions generate a three-dimensional network. |
