Abstract

Self-assembly of the robust Keggin cluster [SiW₁₂O ₄₀]^4- and metalloporphyrin building blocks [M(TpyPH _n)]ⁿ⁺ under hydrothermal conditions gives two new organic-inorganic hybrid solid compounds. The hydrothermal reactions of H₄SiO₄·12WO₃·xH₂O, Cu(NO₃)₂·2.5H₂O, meso-tetra(4-pyridyl) porphine (H₂TpyP) and H₂O at 200 °C for 72 h yield a solid compound [Cu(TpyPH₃)]₂[Cu(TpyPH₂)] [SiW₁₂O₄₀]₂·8H₂O (1). Using ZnCl₂ instead of Cu(NO₃)₂·2.5H ₂O in the syntheses leads to the crystallization of a compound [Zn(TpyPH₄)(H₂O)][SiW₁₂O₄₀] ·3H₂O (2). Both compounds consist of discrete anionic α-[SiW₁₂O₄₀]^4- clusters, cationic metalloporphyrins and crystalline water molecules. Hydrogen bonds, π-π aromatic interactions and CH···π interactions in these two new hybrid solids lead to the formation of 3D framework structures. Pseudo-hexagonal channels are formed by polyoxometalates and are occupied by one-dimensional metalloporphyrin arrays. Both compounds were characterized by single crystal X-ray, UV-Vis, IR spectroscopy and thermogravimetric analysis.
