24-Methylenecholest-4-ene-3β,6β-diol

The title compound, C28H46O2, was isolated from soft coral (Nephthea sp.) collected from Yongxing island of the Xisha archipelago in the South China Sea and its crystal structure has been determined. In the crystal structure, inter­molecular O—H⋯O hydrogen-bond inter­actions link the mol­ecules into extended ribbons parallel to the a axis.
