Inorganic–organic hybrid structures: Synthesis, structure and magnetic properties of a new iron oxalatoarsenate, [NH 3(CH 2)CH(NH 3)CH 3] 3[Fe 6(AsO 4) 2(HAsO 4) 6(C 2O 4) 3]

A hydrothermal reaction of a mixture of iron oxalate, arsenic acid, 1,2-diaminopropane and water at 150 °C gave rise to a new three-dimensional iron oxalatoarsenate, [NH 3(CH 2)CH(NH 3)CH 3] 3[Fe 6(AsO 4) 2(HAsO 4) 6(C 2O 4) 3], I. Crystal data: hexagonal, space group = P-3c1, a = 13.9899 ( 12 ) , c...
