Abstract: The inclusion method was used to isolate a single component from a volatile oil mixture (extracted from the natural medicine, fructus foeniculi) with 1,1,6,6-tetraphenylhexa-2,4-diyne-1,6-diol as the host molecule and 4-methoxybenzaldehyde as the guest (an oil mixture component). Crystals of the host-guest inclusion complex were obtained as C30H22O2·2C8H8O2, with the host molecule residing on a crystallographic inversion centre and connected to the guest molecule by an intermolecular hydrogen bond [OO = 2.846 (5) Å]. The host-guest molecules form a layer-type structure, which extends along the a axis and periodically arranges along the b axis.
