“…Unfortunately, the structure collapses to an amorphous powder after removal of the solvent molecules. For the same tecton, a similar structure was also reported recently by Seidel et al 57 Although the two structures are based on the same ratio of porphyrins in the asymmetric unit and display the same connectivity pattern, they are not isostructural since the solvent molecules present in the structure are not the same.…”

“…Goddard and I. M. Oppel Comment 5,10,15,porphyrin has been widely used as ligand for the construction of coordination polymers (DeVries & Choe, 2009). We and others have reported on the solid-state supramolecular chemistry of the self-complementary [5,10,15,20-tetra(4-pyridyl)porphyrinato]zinc(II) (ZnTPyP) building block (Lipstman & Goldberg, 2010;Seidel et al, 2010 and references cited therein). Recently, we reported the title structure of [ZnTPyP] 4 .…”

“…Small dark red plate-shaped crystals of the title compound were obtained similarly as reported previously (Seidel et al, 2010); 12 mg of ZnTPyP (Aldrich) and 11 mg of [Pd(NO 3 ) 2 (en)] (en = 1,2-diaminoethane) were placed in an ampoule and 4 ml of DMF were added. The ampoule was sealed and placed in a heater.…”

The structure of the title compound, [Zn4(C40H24N8)4]·8C3H7NO·3H2O, has been redetermined at 100 K. The redetermination is of significantly higher precision and gives further insight into the disorder of pyridyl groups and solvent molecules. The molecules of (5,10,15,20-tetra-4-pyridylporphyrinato)zinc(II) (ZnTPyP) form homomolecular cyclic tetramers by coordination of a peripheral pyridyl group to the central Zn atom of an adjacent symmetry-related molecule. The tetramer so formed exhibits molecular S 4 symmetry and is located about a crystallographic fourfold rotoinversion axis. Severely disordered dimethylformamide and water molecules are present in the crystal, the contributions of which were omitted from refinement. Intermolecular C—H⋯N hydrogen bonding is observed.

New pyridinium‐functionalized metalloporphyrins MEtPpBr4 (M = Zn2+, Co2+, Ni2+, Cu2+; EtPp = 5, 10, 15, 20‐tetra(4‐(3‐(N‐ethyl‐4‐pyridyl)pyrazolyl)phenyl)porphyrin) were synthesized as bifunctional catalysts for the cycloaddition reactions of epoxides and CO2. The effects of catalyst loading, CO2 pressure, reaction temperature and time on catalytic activity were investigated. ZnEtPpBr4 (1) and CoEtPpBr4 (2) exhibited efficient activities in the cycloaddition reactions of various epoxides with CO2 as at 120 °C under 2 MPa of CO2 pressure without solvent. Most of corresponding cyclic carbonates could be obtained in almost quantitative yields and > 99.9% selectivity with molar ratio of epoxide/catalyst 2222 after 8 hr of reaction.
