(1Z,1'Z,3E,3'E)-1,1'-Diphenyl-3,3'-[(1S,2S)-cyclo-hexane-1,2-diyldinitrilo]dibut-1-en-1-ol.


ABSTRACT: A new tetra-dentate chiral Schiff base ligand, C(26)H(30)N(2)O(2), has been synthesized by the reaction of 1-phenyl-butane-1,3-dione with (1S,2S)-(-)-1,2-diamino-cyclo-hexane. The chiral centers in the mol-ecule have the same S configuration, since the absolute configuration was determined by that of the starting reagent (1S,2S)-(-)-1,2-diamino-hexane. The cyclo-hexane ring is in a chair conformation, and the substituents are equatorial in the most stable conformation (trans-cyclo-hexyl). The crystal structure is stabilized by two intra-molecular O-H?N hydrogen bonds and a weak C-H?? inter-action.
