The title compound crystallized in the monoclinic space group C2/c with cell parameters a = 30.812(4), b = 10.840(2), c = 12.401(2)Å, β = 106.83(1)°, V = 3964.6(11)Å3, Z = 8, Dcal = 1.278 Mg/m3 at T = 293 K. The structure was solved by direct methods, and refined by full-matrix least-squares procedures to final R = 0.0595 and wR = 0.1867 for 2799 reflections. The steric repulsion between the cyclohexane ring and the phenyl substituents at C2 and C6 makes the bond lengths and bond angles slightly abnormal. The cyclohexane ring adopts a twist-boat conformation and the phenyl rings occupy an equatorial orientation. The carboxylate groups are planar with the end methyl atom deviating from planarity. An inter O-H…N, some C-H…O type of intra and intermolecular and an intra C-H…π interactions play a role in stabilizing the molecules in the unit cell.
