Abstract

The hydrothermal reaction of CoF₂ and 4,4′,4″,4″'-(porphine-5,10,15,20-tetrayl)tetrakis(benzoic acid) (H₆tcpor) provides a mixture of crystalline products, including H₂porph, [Co(porph)] (H₂porph = C₂₀H₁₄N₄), and [Co(H₂O)₃{Co(H₃tcpor)}₂{Co(H₄tcpor)}]·4H₂O (1·4H₂O). Due to the small size, weak diffraction and intergrowth nature of the crystals, the identities of the products were determined using synchrotron single crystal X-ray diffraction. The title compound 1·4H₂O is a tetranuclear cluster of Co(II) sites. Two {Co(H₃tcpor)}^{1 -} and one {Co(H₄tcpor)} subunits radiate from the central {Co(H₂O)₃}^{2 +} moiety of the cluster. Hydrogen bonding stabilizes the central {Co(H₂O)₃(O₂C-)₂(HO₂C-)} core as well as providing extensive three dimensional connectivity between the cluster units.
