In the title compound, C15H19NO4, the cyclo-hexyl ring adopts a chair conformation with both exocyclic C-C bonds in equatorial orientations. The dihedral angle between the basal plane of cyclo-hexyl ring and the 2,4-di-hydroxy-benzaldehyde moiety is 84.13 (13)°. An intra-molecular O-H⋯N hydrogen bonds closes an S(6) ring. In the crystal, Oc-H⋯Op (c = carb-oxy-lic acid, p = phenol) hydrogen bonds link the mol-ecules into [100] C(13) chains whereas an Op-H⋯Oc hydrogen bond generates [101] C(15) chains. Together, these bonds generate (010) sheets incorporating R 2 (2)(20) loops. Weak C-H⋯O and C-H⋯π inter-actions also occur.
在标题化合物C₁₅H₁₉NO₄中，环己基环呈椅式构象，两个环外C-C键均处于平伏取向。环己基环的基面与2,4-二羟基苯甲醛部分之间的二面角为84.13 (13)°。分子内O-H⋯N氢键形成一个S(6)环。在晶体中，Oc-H⋯Op（c = 羧酸，p = 苯酚）氢键将分子连接成[100] C(13)链，而Op-H⋯Oc氢键生成[101] C(15)链。这些键共同形成包含R 2 (2)(20)环的(010)片层。还存在弱的C-H⋯O和C-H⋯π相互作用。
