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. The temperature-limited thermal decomposition of compound 1 under the temperature of boiling toluene (110 ∘C) resulted in the formation of (NH4)4Co2Mn6O12. which contains a todorokite-like manganese oxide network (MnII4MnIII2O1210−). The heat treatment products of compounds 1 and [Co(NH3)5Cl](MnO4)2 (2) synthesized previously at 500 ∘C were a cubic and a tetragonal spinel with Co1.5Mn1.5O4 and CoMn2O4 composition, respectively. 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 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 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 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.}, year = {2022}, eissn = {2304-6740}, orcid-numbers = {Béres, Kende Attila/0000-0003-4257-0581; Farkas, Attila/0000-0002-8877-2587; Holló, Berta Barta/0000-0002-5786-442X} } @{MTMT:33299135, title = {Pyridinesilver Tetraoxometallate Complexes: Overview of the Synthesis, Structure, and Properties of Pyridine Complexed AgXO4 (X = Cl, Mn, Re) Compounds}, url = {https://m2.mtmt.hu/api/publication/33299135}, isbn = {9783036557052}, author = {Paiva Franguelli, Fernanda and Béres, Kende Attila and Kótai, László}, booktitle = {Cornerstones in Contemporary Inorganic Chemistry}, unique-id = {33299135}, year = {2022}, pages = {251-263}, orcid-numbers = {Béres, Kende Attila/0000-0003-4257-0581} } @article{MTMT:32651012, title = {Multi-Centered Solid-Phase Quasi-Intramolecular Redox Reactions of [(Chlorido)Pentaamminecobalt(III)] Permanganate—An Easy Route to Prepare Phase Pure CoMn2O4 Spinel}, url = {https://m2.mtmt.hu/api/publication/32651012}, author = {Paiva Franguelli, Fernanda and Kováts, Éva and Czégény, Zsuzsanna and Nagyné Bereczki, Laura and Petruševski, Vladimir M. and Holló, Berta Barta and Béres, Kende Attila and Farkas, Attila and Szilágyi, Imre Miklós and Kótai, László}, doi = {10.3390/inorganics10020018}, journal-iso = {INORGANICS}, journal = {INORGANICS}, volume = {10}, unique-id = {32651012}, year = {2022}, eissn = {2304-6740}, orcid-numbers = {Petruševski, Vladimir M./0000-0002-4796-4929; Béres, Kende Attila/0000-0003-4257-0581; Farkas, Attila/0000-0002-8877-2587; Szilágyi, Imre Miklós/0000-0002-5938-8543} } @article{MTMT:32479754, title = {Pyridinesilver Tetraoxometallate Complexes: Overview of the Synthesis, Structure, and Properties of Pyridine Complexed AgXO4 (X = Cl, Mn, Re) Compounds}, url = {https://m2.mtmt.hu/api/publication/32479754}, author = {Paiva Franguelli, Fernanda and Béres, Kende Attila and Kótai, László}, doi = {10.3390/inorganics9110079}, journal-iso = {INORGANICS}, journal = {INORGANICS}, volume = {9}, unique-id = {32479754}, abstract = {We reviewed the synthesis, structure, and properties of pyridine complexes of AgXO4 (X = Cl, Mn, and Re) compounds with various compositions ([AgPy2 ] XO4, [AgPy2 XO4 ]·0.5Py, [AgPy4 ] XO4, and 4 [AgPy2 XO4 ] [AgPy4 ] XO4 ).
