The base form of the local anaesthetic kazcaine (BFK, [1-(2-ethoxyethyl)-4-ethynyl-4-benzoyloxypiperidine, C(18)H(23)NO(3)]) and beta-cyclodextrin (beta-CD) co-crystallized as BFK:beta-CD inclusion complex in 1:2 M ratio from a mixture of water and ethanol while the filtered mother liquor yielded crystals of free BFK. X-ray diffraction showed that the crystals of BFK and its inclusion complex with beta-CD belong to monoclinic (P2(1)/c) and triclinic (P1) space groups, respectively. The crystals of free BFK are stabilized by pairs of C-Ha
