6,6′-Dimethoxy-2,2′-[(1R,2R)-cyclohexane-1,2-diylbis(nitrilomethylidyne)]diphenol: three C—H...O hydrogen bonds generate a three-dimensional framework

Abstract

Molecules of the title compound, alternatively called (R,R)-N,N'-bis(3-methoxysalicylidene)-trans-cyclohexane-1,2-diamine, C(22)H(26)N(2)O(4), contain two intramolecular O-H.N hydrogen bonds and adopt a conformation with approximate twofold rotational symmetry. The molecules are linked by three C-H.O hydrogen bonds [H.O = 2.45-2.55 A, C.O = 3.329 (2)-3.398 (2) A and C-H.O = 142-172 degrees ] into a continuous framework.
