The title compound, [Cu(CH(3)COO)(2)(C(7)H(9)NO)(2)], is a monomeric complex with an octa-hedral geometry. The Cu(II) atom is located on an inversion center and is coordinated by acetate and 2-(pyridin-2-yl)ethanol ligands. The acetate group is coordinated in a monodentate manner, while the 2-(pyridin-2-yl)ethanol is coordinated as a bidentate ligand involving the endocyclic N atom and the hy-droxy O atom of the ligand side chain. An intra-molecular hydrogen bond is observed between the hy-droxy O atom and the non-coordinated acetate O atom. No classical inter-molecular hydrogen-bond contacts were observed. However, the crystal packing is effected by C-H⋯O inter-actions, which link the mononuclear entities into layers parallel to the bc plane.

The title compound, (CHNO)[CuCl(CHNO)]·2HO, was prepared by reacting Cu acetate dihydrate, solid 8-hy-droxy-quinoline (8-HQ), and solid pyridine-2,6-di-carb-oxy-lic acid (Hpydc), in a 1:1:1 molar ratio, in an aqueous solution of dilute hydro-chloric acid. The Cu atom exhibits a distorted CuONCl octa-hedral geometry, coordinating two oxygen atoms and one nitro-gen atom from the tridentate Hpydc ligand and three chloride atoms; the nitro-gen atom and one chloride atom occupy the axial positions with Cu-N and Cu-Cl bond lengths of 2.011 (2) Å and 2.

The title compound, CHNO, is a hy-droxy-substituted mono-amine alkaloid, and the primary metabolite of the naturally occurring psychedelic compound psilocybin. Crystalline forms of psilocin are known, but their characterization by single-crystal structure analysis is limited. Herein, two anhydrous polymorphic forms (I and II) of psilocin are described.
