| Abstract | A sandwich-type tungstophosphate, (1,3-H(2)dap)(2)H-4[Co-4 (1,3-Hdap)(2)(alpha-B-PW9O34)(2)]center dot 3H(2)O (1,3-dap = 1,3-diaminopropane), was hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental and thermo-gravimetric analysis, and IR and UV spectroscopy. The compound presents a classical tetra-transition metal-substituted sandwich framework, [Co-4(1,3-Hdap)(2)(alpha-B-PW9O34)(2)](8-), which contains two lacunary alpha-B-[PW9O34](9-) Keggin units linked by a rhomb-like Co4O14(1,3-dap)(2) cluster lying across an inversion center. The Co2+ ions are coordinated by a mono-protonated dap ligand. Isolatedly protonated 1,3-dap units act as counter-ions interacting with the [PW9O34](9-) polyanions via hydrogen bonds forming a three-dimensional framework. |
