Electron-overdoped Ag(II)F2: mixed-valence fluorides Ag(I)Ag(II)F3 and Ag(I)2Ag(II)F4
Katarzyna Kuder, Kacper Koteras, Zoran Mazej +1
We have successfully prepared two novel mixed-valence compounds of silver, Ag(I)Ag(II)F3 and Ag(I)2Ag(II)F4. They may be considered to be long-sought strongly electron-overdoped Ag…
Novel Ternary AgIICoIIIF5 Fluoride: Synthesis, Structure and Magnetic Characteristics
Daniel Jezierski, Zoran Mazej, Wojciech Grochala
We present a new compound in the silver cobalt fluoride system, featuring paramagnetic silver (d9) and high-spin cobalt (d6), synthesized by solid state method in an autoclave unde…
A unique two-dimensional silver(II) antiferromagnet Cu[Ag(SO4)2] and perspectives for its further modifications
Mateusz Domanski, Zoran Mazej, Wojciech Grochala
Copper(II) silver(II) sulfate crystallizes in a monoclinic CuSO4-related structure with P21/n symmetry. This quasi-ternary compound features [Ag(SO4)2]2- layers, while the remainin…
Unexpected coexisting solid solutions in the quasi-binary Ag(II)F2/Cu(II)F2 phase diagram
D. Jezierski, K. Koteras, M. Domanski +4
High-temperature solid-state reaction between orthorhombic AgF2 and monoclinic CuF2 (y = 0.15, 0.3, 0.4, 0.5) in a fluorine atmosphere resulted in coexisting solid solutions of Cu-…
New CuSO4-related high-temperature polymorph of AgIISO4
Mateusz Domanski, Zoran Mazej, Wojciech Grochala
Silver(II) compounds exhibit powerful oxidizing properties and strong magnetic superexchange. AgSO4 is a rare fluorine-free salt of Ag(II) which found some application in organic c…
Phase transitions and amorphization of M2AgF4 (M = Na, K, Rb) compounds at high pressure
Jakub Gawraczynski, Łukasz Wolanski, Adam Grzelak +3
We report the results of Raman spectroscopy high-pressure studies of alkali metal fluoroargentates (M2AgF4, where M=Na, K, Rb) associated with theoretical and x-ray diffraction stu…
Crystal structure, lattice dynamics and superexchange in MAgF3 1D antiferromagnets (M = K, Rb, Cs) and Rb3Ag2F7 Ruddlesden-Popper phase
Kacper Koteras, Jakub Gawraczynski, Gasper Tavcar +2
With the use of lattice dynamics calculation within hybrid HSE06 framework we were able to understand vibrational spectra of MAgF3 M = K, Rb, Cs compounds. Comparative theoretical…
NaZnF3 as a low-pressure analogue of MgSiO3
Dominik Kurzydłowski, Arkadiusz Gajek, Zoran Mazej
Solid-state systems whose properties at high pressure (exceeding 1 GPa) mimic those of MgSiO3 are of large importance in the study of the interior of planets. By means of Density F…
Lattice dynamics of KAgF3 perovskite, unique 1D antiferromagnet
Kacper Koteras, Jakub Gawraczynski, Mariana Derzsi +2
Theoretical DFT calculations using GGA+U and HSE06 frameworks enabled vibrational mode assignment and partial (atomic) phonon DOS determination in KAgF3 perovskite, a low-dimension…
Unexpected persistence of cis-bridged chains in compressed AuF3
Dominik Kurzydłowski, Serhiy Kobyakov, Zoran Mazej +3
Raman scattering measurements indicate that cis-bridged chains are retained in AuF3 even at a compression of 45 GPa - in contrast to meta-GGA calculations suggesting that structure…
