(E)-16-(4-Chloro­benzyl­idene)estrone

In the title compound, C(25)H(25)ClO(2), the C ring adopts a chair conformation, while the B ring approximates a half-chair conformation. The five-membered ring D has a twist con­form­ation on the C—C bond fused with the C ring. Aromatic rings A and E are not coplanar, as evidenced by the dihedral a...

description In the title compound, C(25)H(25)ClO(2), the C ring adopts a chair conformation, while the B ring approximates a half-chair conformation. The five-membered ring D has a twist con­form­ation on the C—C bond fused with the C ring. Aromatic rings A and E are not coplanar, as evidenced by the dihedral angle of 7.51 (1)°. In the crystal, O—H⋯O hydrogen bonds form a double chain along the ab plane inter­connected by C—H⋯O inter­actions.
