![]() Persulfate anions is stabilized by extended intramolecular (N–H⋯O = C) and intermolecular (N–H⋯O–S) hydrogen bonds. The octahedral arrangement of the complex cation and its packing with two crystallographically different Six crystallographically different urea ligands coordinate via their oxygen in a propeller-like arrangement to iron(III) forming a distorted octahedral complex cation. The todorokite-like intermediate prepared from compound 1 under N2 at 115 ∘C resulted in a 54 times faster degradation of Congo red, which is a great deal faster than the same todorokite-like phase that formed from compound 2 under N2.Īnhydrous hexakis(urea-O)iron(III)]peroxydisulfate (2(S2O8)3 (compound 1), and its deuterated form were prepared and characterized with single-crystal X-ray diffraction and spectroscopic (IR, Raman, UV, and Mössbauer) methods. The decomposition rate of the dye was found to be nine times faster than in the presence of the tetragonal CoMn2O4 spinel prepared in the solid-phase decomposition of compound 2. The Co1.5Mn1.5O4 prepared from compound 1 at 500 ∘C during the solid-phase decomposition catalyzes the degradation of Congo red with UV light. The heating of the decomposition product of compounds 1 and 2 that formed under refluxing toluene (a mixture with an atomic ratio of Co:Mn = 1:1 and 1:2) and after aqueous leaching ((NH4)4Co2Mn6O12, 1:3 Co:Mn atomic ratio in both cases) at 500 ∘C resulted in tetragonal Co0.75Mn2.25O4 spinels. The heat treatment products of compounds 1 and (MnO4)2 (2) synthesized previously at 500 ∘C were a cubic and a tetragonal spinel with Co1.5Mn1.5O4 and CoMn2O4 composition, respectively. ![]() which contains a todorokite-like manganese oxide network (MnII4MnIII2O1210−). The temperature-limited thermal decomposition of compound 1 under the temperature of boiling toluene (110 ∘C) resulted in the formation of (NH4)4Co2Mn6O12. The 3D−hydrogen bond network includes N–HO–Mn and N–HCl interactions responsible for solid-phase redox reactions between the permanganate anions and ammonia ligands.

Weigh a sample bottle and record its mass.The dry solid should powder easily and not be clumpy. Test for dryness by turning over the solid using a spatula. Dry the solid by leaving the aspirator on to pull air through the funnel. Finally, rinse the crystals with cold ethanol. Wash out the test tube with cold ethanol and add to the Buchner funnel. Filter the crystals by vacuum filtration.Pour 6 cm 3 of ethanol into a beaker and transfer the contents of the test tube into the beaker of ethanol, mix then cool the mixture actual yield using the crushed ice.Add while stirring, 2 cm 3 of conc ammonia solution to the copper(II)sulphate solution.N.B: Do the next step in the fume cupboard while wearing gloves.
