In an attempt to synthesize new cobalt(II) sulfate framework structures using 1,4-diazabicyclo[2.2.2]octane as a template, crystals of poly[0.35-[hexaaquacobalt(II)] [tri-μ-hydroxido-μ-sulfato-dicobalt(II)]], {[Co(H 2 O) 6 ] 0.35 [Co 2 (OH) 3 (SO 4 )]} n , were obtained as a mixture with [Co(H 2 O) 6 ]SO 4 crystals. The crystal structure can be described as being constructed from discrete brucite-type [Co 4 (OH) 6 (SO 4 ) 2 ] layers, each of which is built up from edge-shared [Co(OH) 6 ] and [Co(OH) 4 -(OSO 3 ) 2 ] octahedra, with partial intercalation by [Co(H 2 O) 6 ] 2+ ions. The absence of ca 30% of the [Co(H 2 O) 6 ] 2+ cations indicates partial oxidation of cobalt(II) to cobalt(III) within the layer.
