2-(1,3-Dithian-2-yl)benzaldehyde and N-{2-[2-(1,3-dioxan-2-yl)phenoxy]­ethyl}phthalimide

The crystal structures of two elaborated-porphyrin precursors have been determined. In the crystalline state, 2-(1,3-di­thian-2-yl)­benz­aldehyde, C₁₁H₁₂OS₂, has its di­thiane ring in a slightly distorted chair conformation. The mol­ecules pack in anti-parallel chains. N-{2-[2-(1,3-Dioxan-2-yl)­phenoxy]­ethyl}­phthal­imide, C₂₀H₁₉NO₅, is in a folded conformation. The dihedral angle between the phthal­imide and phenyl planes is 80.07 (3)°. In the crystalline states, mol­ecules stack on top of one another.
